CA Service Management

Hi,

I need to enable SSO for CABI 4.1 using windows authetication using IIS. Can anyone help me with this.

BusinessObjects 4.0 Single Sign On

First thing first.

Define server name and IP address.

Run following commands to return server names and IPs.

• Domain Name: DOMAIN (FQDN: DOMAIN.INTERNAL)
• Service Account: biservice (password: Password1)
• Domain Controller: adserver.DOMAIN.INTERNAL
• BusinessObjects Server: <Your Server>.DOMAIN.INTERNAL
• BusinessObjects AD Group: DOMAIN\UserGroup

Step 1 

Create an Active Directory service account, biservice (password: Password1). Make to set this user password never expireAdd Domain/biservice user to local Administrators group and assign biservice user the right 'Act as part of Operating System' in the Local Security Policy snap-in

Step 2In order to create appropriate Service Principal Names (SPNs), execute the following commands on Active Directory server:

• setspn -a BICMS/biservice.domain.internal biservice
• setspn -a HTTP/bi4server biservice
• setspn -a HTTP/bi4server.domain.internal biservice

  Run ‘setspn -l biservice’to confirm SPNs have been created by running 

Step 3Make sure to change the user config of ‘biservice’ user in Active Directory configuration, and under the Delegation tab, turn on ‘Trust this user for delegation to any service (Kerberos only)’.

Step 4In Central Management Console CMC under AD Authentication area perform the following tasks.

• AD Administration Name = DOMAIN\biservice
• Default AD Domain: DOMAIN.INTERNAL
• Add AD Group: DOMAIN\UserGroup
• Use Kerberos Authentication
• Service principal name = BICMS/biservice.domain.internal
• Enable Single Sign On for selected authentication mode

  Hit Save to save all your entries. Also make sure to check under the Groups area to make sure your AD group has been added. 

Step 5Modify the Server Intelligence Agent (SIA) process on the BusinessObjects server to run as the DOMAIN\biservice user.

1. Stop SIA
2. RMC on SIA and Properties
3. Go to configuration
4. Under Log on as enter your credential
5. User: DOMAIN\biservice and password
6. Click OK and start the service

Step 6Here we can test this by logging into Web Intelligence Rich Client using an AD user who is part of the group. Single Sign On (SSO) should take place once you select ‘Windows AD’ authentication and click OK (There is no need to input your username or password).

Step 7Now it is turn to create a file called ‘bscLogin.conf’. Save this file to C:\Windows\ directory on the BusinessObjects server, and put the following content into it using Notepad:

com.businessobjects.security.jgss.initiate {com.sun.security.auth.module.Krb5LoginModule required debug=true;

};

We are not done yet. Create another file called ‘krb5.ini’. Save this file to C:\Windows\ directory, and put the following content into it using Notepad:

[libdefaults]default_realm = DOMAIN.INTERNAL

dns_lookup_kdc = truedns_lookup_realm = true

default_tgs_enctypes = rc4-hmacdefault_tkt_enctypes = rc4-hmac

udp_preference_limit = 1[realms]

1. DOMAIN.INTERNAL ={

kdc = ADSERVER.DOMAIN.INTERNALdefault_domain = DOMAIN.INTERNAL

}

Make sure this file is save correctly by navigating to E:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win64_x64\jdk\bin\ folder on the BusinessObjects server, and execute ‘kinit biservice’ in a command prompt. If a new ticket is stored, the file is correct.

Step 8Here are we now on BOBJ Server.

Stop Tomcat. Modify the BI Launch Pad’s .properties file to reveal the authentication dropdown. Navigate to E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\webapps\BOE\WEB-INF\custom and create a file called ‘BIlaunchpad.properties’ with the following text:authentication.visible=true

authentication.default=secWinAD

Open up the Tomcat Options, and add the following lines to the Tomcat Java Options:

1. Start > Tomcat > Tomcat Configuration
2. Go to Java Tab
3. Enter the following code under Java Option at the end or previously entered commands (Don’t delete previous commands
4. Click Apply

-Djava.security.auth.login.config=c:\windows\bscLogin.conf-Djava.security.krb5.conf=c:\windows\krb5.ini

Once you are done there, Start Tomcat and do a manual logon to BusinessObjects, and check Tomcat trace logs for a ‘commit succeeded’.

Step 9Stop Tomcat. Modify E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\conf\server.xml, by adding ‘maxHttpHeaderSize=”65536″‘ in Connector Port 8080 tag.

Navigate to E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\webapps\BOE\WEB-INF\config\custom and create a file called ‘global.properties’ with the following text:sso.enabled=true

siteminder.enabled=falsevintela.enabled=true

idm.realm=DOMAIN.INTERNALidm.princ=biservice

idm.allowUnsecured=trueidm.allowNTLM=false

idm.logger.name=simpleidm.logger.props=error-log.properties

Open Tomcat Options Add the following lines to Tomcat Java Options:

-Dcom.wedgetail.idm.sso.password=Password1-Djcsi.kerberos.debug=true

Delete logs in E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\logs\ and C:\SBOPWebapp_BIlaunchpad_IP_PORT\.Start Tomcat, go to E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\logs\, check stdout.log has ‘credentials obtained’ shown.

Test silent single sign on is now working in a browser (not on the BusinessObjects server).

Step 10Copy BIlaunchpad.properties and global.properties from E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\webapps\BOE\WEB-INF\config\custom to E:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\warfiles\webapps\BOE\WEB-INF\config\custom so that patches don’t overwrite them and SSO stops working.

Step 11Create a keytab on the AD server by running the following command:

ktpass -out bosso.keytab -princ biservice@DOMAIN.INTERNAL -pass Password1 -kvno 255 -ptype KRB5_NT_PRINCIPAL -crypto RC4-HMAC-NTCopy this file to c:\windows of BOBJ server.

Stop Tomcat.Add the following line to E:\Program Files (x86)\SAP BusinessObjects\Tomcat6\webapps\BOE\WEB-INF\config\custom\global.properties

1. idm.keytab=C:/WINDOWS/bosso.keytab

Open Tomcat Configuration, remove the Wedgetail line in Java Options, restart tomcat and make sure ‘credentials obtained’ still showing up in stdout.log.Now check silent single sign on.

Step 12Remove debug=true from the C:\windows\bscLogin.conf file, and also remove the debugging line in Tomcat Configuration, Java Options.

1. Stop Tomcat
2. RMC on Tomcat and click Properties
3. Go to Java tab
4. Remove debug = true from there

Conclusion

I hope these steps will give a bird's eye view to know how to setup SSO in WIN AD environment with BusinessObjects 4.0

Don’t forget to look at SAP note 1631734. SAP notes contain troubleshooting help for each given step.

Hi Bashir,

Thanks for the reply. Do you have the method to be followed for enabling SSO in CABI 4.1 using IIS. The above method uses Tomcat I believe.
