Executive Summary This white paper explains how a desktop-based application such as My Documentum for Microsoft Outlook can work in a certificate-based mode of authentication provided by CA SiteMinder®. This paper covers the configurations that must be performed on the SiteMinder Policy Server, Web Agent, Web Server and the My Documentum for Microsoft Outlook server to enable authentication using a sample set of self-signed certificates created using OpenSSL.

This paper also covers troubleshooting setup and other known issues.

Audience

This paper is intended for those who are responsible for integrating My Documentum for Microsoft Outlook with CA SiteMinder® for certificate-based mode of authentication.

Certificate-based Authentication and My Documentum for Microsoft Outlook

CA SiteMinder Overview

SiteMinder provides centralized security management an enterprise needs to authenticate users and control access to web applications and portals. This ensures protection of high-value applications using stronger authentication methods, while lower-value applications may be protected using simple user name and password approaches. CA SiteMinder provides access management support to many authentication systems including passwords, tokens, X.509 certificates, smartcards, custom forms, biometrics and combinations of authentication methods.

Figure 1 illustrates the major components of SiteMinder.



Figure 1. SiteMinder components

SiteMinder components

Policy Server: The Policy Server acts as a decision point and validates user credentials against stored access control policies. It then communicates status information with the Web Agent.

Web Agent: The Web Agent intercepts the request to access a resource and checks the Policy Server to determine whether the resource is protected. If the resource is protected, the Web Agent communicates with the Policy Server to authenticate and authorize the user. It caches information about authenticated users to allow quicker access.

Policy Store: The Policy Store stores all policy related objects including resources that SiteMinder protects, users or groups that cannot access those resources, and actions to take when users are granted or denied access.

User Store: The User Store represents an existing user directory for an organization. It contains user and group information, passwords, and attributes. The Policy Server uses the User Store to authenticate users.

Authenticating using certificates

Certificate-based authentication is one of the authentication schemes supported by SiteMinder. This scheme of authentication considers the X.509 client certificate as a proof of the user’s identity. The X.509 client certificate is unique for each user and contains the following information:

Name or Distinguished Name (DN) Public key Name of Certificate Authority (CA) who issued the certificate

The X.509 server certificate is installed on the web server where secure sockets layer (SSL) is enabled. The certificates must be issued by a valid and trusted Certificate



Authority and must not yet have expired. The public key of the issuing CA must validate the issuer’s digital signature, and the user’s public key must validate the user’s digital signature.

The first step in this authentication scheme is to establish an SSL connection with the web server or proxy on which the web agent is installed. When the SSL connection is successfully established, the details in the certificate are sent to the Policy Server for verification against the information in the user store.

SiteMinder uses certificate mapping to determine how to compare a user's certificate with the information stored in the user directory. Certificate mapping defines how data in the certificate is mapped to form a user Distinguished Name (DN). The Policy Server uses this user DN to authenticate the user. If certificates are stored in an LDAP directory, a certificate mapping can direct the Policy Server to verify that the certificate provided by the user matches the certificate associated with the user DN in the LDAP directory.

My Documentum for Microsoft Outlook and CA SiteMinder

My Documentum for Microsoft Outlook supports only certificate-based authentication in SiteMinder. It uses the client certificates installed in the Windows Keystore to encrypt the request. The server can decrypt the request and verify it’s validity using the CA public key installed on it. The certificate details are passed to the Policy Server that verifies user credentials in LDAP. After successful authentication, an SMSESSION cookie is created and the request is passed to the My Documentum for Microsoft Outlook server, for processing.

The My Documentum for Microsoft Outlook application server passes the cookie to Content Server. Content Server verifies the user credentials with the Policy Server using the cookie value and authenticates the user to the repository. The certificate user name and the repository username must be the same for the authentication to be successful on Content Server.



Figure 2. My Documentum for Microsoft Outlook and SiteMinder interaction

Creating and installing the certificate OpenSSL is an open source implementation of SSL and TLS. The sample certificates created with this tool will be used further for the integration of My Documentum for Microsoft Outlook with SiteMinder.

Creating certificates using OpenSSL

The X.509 certificate contains the public key and binds it with the holder’s identity.

To create a certificate authority: 1. Create an RSA private key as follows:

> openssl genrsa -des3 -out private/ca.key 1024

The “genrsa” command generates an RSA private key.

-des3 : This option encrypts the private key with Triple DES cipher.

-out : The output file name.

“1024” : gives the size of the private key to be generated.

The user is prompted to specify a passphrase or password. The ca.key is placed in the private folder.

2. Create an X.509 certificate and sign using a private key as follows: > openssl req -new -x509 -key private/ca.key -out public/ca.crt -days 3600



The “req” command primarily creates and processes certificate requests in PKCS#10 format.

-new : This option generates a new certificate request.

-key : This specifies the file to read the private key from.

-out : This specifies the output filename to write to or standard output by default.

The user is prompted to enter details such as country name and organization. The Common Name or CN and the identify of the user must be unique. The “ca.crt” CA certificate is created.

To create certificate for server machine and sign with CA: 1. Create an RSA private key for server as follows:

> openssl genrsa -des3 -out private/server.key 1024

2. Create the Certificate Signing Request , > openssl req -new -key private/server.key -out server.csr

3. Sign the certificate with the CA’s private key, > openssl x509 -req -days 360 -in server.csr -CA public/ca.crt -CAkey private/ca.key - CAcreateserial -out public/server.crt

When the x509 utility is used to sign certificates and requests, the utility behaves like a mini Certifying Authority.

-req: Requires a certificate request as input.

-days: Denotes the number of days for which the certificate is valid.

-in: Specifies the input filename from which a request is read. A request is read only if the creation options (-new and -newkey) are not specified.

-CA: Specifies the CA certificate to use for signing. The CA signs this input file using this option. Its issuer name is set to the subject name of the CA, and it is digitally signed using the private key of the CA.

-CAkey: Sets the CA private key with which a certificate is signed.

-CAcreateserial: Creates the CA serial number file if it does not exist.

-out: Specifies the output filename to write

The Common Name for the sever certificate must be a Fully Qualified Domain Name of the server machine.

To create an X.509 certificate for a user or client and sign it with a private key: 1. Create a client private key and generate a request as follows:

> openssl req -new -newkey rsa:1024 -nodes -out client/client.req -keyout client/client.key

2. Create an X.509 certificate and sign it using CA as follows:



> openssl x509 -CA public/ca.crt -CAkey private/ca.key -CAserial public/ca.srl -req -in client/client.req -out client/client.pem -days 100

The output is a .pem file that is converted to the pkcs12 format.

3. Convert the .pem file to the pkcs12 format as follows:

> openssl pkcs12 -export -clcerts -in client/client.pem -inkey client/client.key -out client/client.p12 -name <your_certificate_name>

The pkcs12 command creates and parses PKCS#12 files (sometimes referred to as PFX files).

-export: Specifies that a PKCS#12 file is created and not parsed.

-in: Specifies the filename from which the certificates and private keys are read. Specifies the standard input, by default.

-inkey: Specifies the file from which the private key is read.

-out: Specifies the filename of the file in to which certificates and private keys are written.

-name: Specifies the ``friendly name'' of the certificate and private key. This name is typically displayed in list boxes by the software that imports the file.

The client.p12 is the client certificate in the pkcs12 format. It stores the private key and public key of the client.

Figure 3. client.p12 Client Certificate Structure

Installing certificates in the Windows Key Store

The client certificate in the pkcs12 format (client.p12) must be installed on the client machine (see Figure 2) for My Documentum for Microsoft Outlook to successfully authenticate to the server.

Web agent and web server

This section provides steps to configure an Apache web server, and the Web Agent installed on the Apache web server.

Configuring the Apache web server

After installing the Apache web server, configure it with a 2-way Secure Socket Layer (SSL) by modifying the httpd.conf file available in the <Apache2 home>\conf directory.

Open the httpd.conf file and uncomment the following lines so that the modules are loaded:

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_connect_module modules/mod_proxy_connect.so

LoadModule proxy_http_module modules/mod_proxy_http.so

LoadModule proxy_ftp_module modules/mod_proxy_ftp.so

LoadModule ssl_module modules/mod_ssl.so



Add the Listener port to enable SSL:

Listen 443

Turn the SSL Engine by adding the following lines to the httpd.conf file:

SSLEngine on

SSLCertificateFile <path to server .crt file including the file name>

SSLCertificateKeyFile <path to server .key file including name>

SSLOptions +StdEnvVars +CompatEnvVars

SSLVerifyClient optional

SSLVerifyDepth 10

SSLCACertificateFile <path to CA .crt file including name>

Note: You can add these lines separately in the <Apache2 home>\conf\ssl.conf file.

Add the following lines to configure reverse proxy for the My Documentum for Microsoft Outlook application server:

ProxyRequests Off

ProxyPass /dco http://<ip address>:<port>/dco

To configure the web agent: 1. Run the web agent installer or if it is already installed, select Start > SiteMinder >

Web Agent Configuration Wizard. The Host Registration dialog box appears.

2. Select “Yes, I would like to do Host Registration now.”.

3. Click Next.

4. Specify the SiteMinder admin user name and password details.

5. Click Next.



Figure 19. Enter SiteMinder administrator user name and password

6. In the Trusted Host Name field specify the fully qualified name of the machine on which the web agent is installed.

7. In the Host Configuration Object field, specify the name of the host configuration object created in the Policy Server. This field is case-sensitive. Ensure that the name matches the Host Configuration Object created in Policy Server as this field is case-sensitive.

8. Click Next.



Figure 20. Specify Host Name and Host Configuration Object

9. Enter the IP address of the Policy Server machine and click Add.

10. Click Next.

11. Change the Host configuration file location or retain the default values.

12. Click Next. A list of web servers is displayed.

13. Select the Apache server that must be configured with the web agent.

14. Click Next.



Figure 21. Specify Agent Configuration Object

15. Enter the name of the Agent Configuration Object created in the Policy Server.

16. Click Next. The SSL authentication dialog box appears.

Figure 22. Select the authentication scheme



17. Select the X509 Client Certificate or Form configuration. My Documentum for Microsoft Outlook does not work with Form-based authentication.

18. Click Next. The Self Registration dialog box appears.

19. Select No, I don’t want to configure Self Registration.

20. Click Next.

After the web agent is installed, verify the http.conf file to ensure it contains the following entries:

LoadModule sm_module "<web agent home under program files>/ bin /mod_sm20.dll"

SmInitFile "<apache home>/conf/WebAgent.conf"

Ensure that the WebAgent.conf file is created in the <apache home> directory.

Open the WebAgent.conf file and add the following line:

PreservePostData="NO"

Add this line to disable the Preserve Post Data feature that shows an alternate page on the browser to hold the credential data when redirected. Since My Documentum for Microsoft Outlook does not have a browser interface, set the value of the PreservePostData property to No.

Enable the web agent in the WebAgent.conf file by modifying the EnableWebAgent property as follows:

EnableWebAgent="YES"

The client works in a 2-way SSL mode with the web server if the web agent is disabled.

Configurations in Documentum Content Server and My Documentum for Microsoft Outlook server

Configuring Content Server

Documentum Content Server is installed with SiteMinder plug-ins.

To enable SiteMinder SSO on Content Server:

1. Copy the following dlls from $DM_HOME/install/external_apps/auth_plugins/Netegrity to $DOCUMENTUM/dba/auth:

Windows

dm_netegrity_auth.dll smagentapi.dll smerrlog.dll

Solaris/AIX/LINUX

dm_netegrity_auth.so



libsmagentapi.so libsmerrlog.so libsmcommonutil.so

For HPUX

dm_netegrity_auth.sl libsmagentapi.sl libsmerrlog.sl

2. Edit $DOCUMENTUM/dba/auth/dm_netegrity_auth.ini to include the following information:

agent_name = <name of Agent Object created in Policy Server>

shared_secret = <password of the Agent in Policy Server>

policy_server_ip = <IP of Policy Server>

resource=/dco

Content Server uses this information to verify whether the Policy Server has authenticated the user.

3. Restart the repository to ensure the changes are applied. Verify the repository log file to check if errors occurred while the plug-in was loaded.

Configuring the My Documentum for Microsoft Outlook server

Modify the dfs-sso-config.properties file available in emc-dfs-rt.jar in the WEB_INF/lib folder with SSO type information. SiteMinder properties are as follows:

sso.type = dm_netegrity

user.header.name = SM_USER

password.cookie.name = SMSESSION

After performing the required modifications, repackage the updated emc-dfs-rt.jar file in the My Documentum for Microsoft Outlook EAR file.

Testing the setup

After performing the setup, you are recommended to verify client authentication using a browser before accessing it through the MS Outlook client as follows:

Verify whether the SSL mode works without enabling the web agent on the proxy or web server using a browser to access the My Documentum for Microsoft Outlook URL. If this test passes, then the server and client certificates are correct. Otherwise, check if the certificates are valid and whether they are installed or referenced in the appropriate locations on both the client and server.

After enabling the web agent in the WebAgent.conf file, using a browser verify whether the Policy Server authenticates the user with the client certificate. If it fails to authenticate the user, check the Policy Server and web agent configurations, especially the Certificate Mapping on the Policy Server.



Specify the web server URL in the My Documentum for Microsoft Outlook client and try to connect to the URL. If the connection fails, check for errors in the %appdata%/SSOComponent/sso.log file in the My Documentum for Microsoft Outlook client.

After the initial test passes in My Documentum for Microsoft Outlook, the repository login dialog box appears. The user name and password fields are disabled. Verify whether the username is correct and click OK. If the login fails, enable authentication trace logs on Content Server to obtain additional information. Further, verify whether the dfs-sso-config.properties file in the My Documentum for Microsoft Outlook server contains the correct values.

Troubleshooting

Error in apache proxy

The following error indicates that the passphrase must be removed from the server certificate:

[error] Init: SSLPassPhraseDialog builtin is not supported on Win32 (key file <some keyfile name>)

Remove the passphrase from the server certificate using the following command:

openssl rsa -in server.key -out server.key

Where server.key is the private key of the server machine.

Error when using “req” command in OpenSSL

The following error occurs during the creation of X.509 certificates:

Unable to load config info from /usr/local/ssl/openssl.cnf

error in req

Run the req command after appending the following content:

–config “< path to openssl.cfg >”

The openssl.cfg file is available in the OpenSSL/bin folder.

Conclusion This white paper provides details about the authentication mechanism to enable certificate-based authentication by a desktop client, such as My Documentum for Microsoft Outlook.

The white paper also provides a brief overview of creating certificates using X.509 and the configuration changes necessary for each component to ensure My Documentum for Microsoft Outlook works seamlessly in a certificate-based SiteMinder setup.
