Initial edit of IBM CMOD & DB2 with winbind LDAP authentication.

{{TOCright}}
While technically unsupported, it is possible to configure DB2 to work with [https://www.samba.org/samba/what_is_samba.html SAMBA] [https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Domain_Member Winbind] on UNIX operating systems.

DB2 with winbind isn't explicitly supported: [https://www-01.ibm.com/support/docview.wss?uid=swg21587206 IBM Technote: Does DB2 support Samba Winbind authentication from Linux?] (This specific article is 3+ years old at the time this article was written. A request to update it has been submitted.)

If you're reading this article because you need to configure a Linux server with DB2 using SAMBA winbind for LDAP authentication, start with the [http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/winbind.html SAMBA winbind on Linux HOWTO document]

==What were you doing?==
Probably trying to complete an IBM CMOD installation on a new machine with centralized authentication (using [[Glossary#Acronyms|LDAP]]) with the open-source SAMBA winbind library. Alternatively, your organization may have tried to implement LDAP with SAMBA winbind on an existing OnDemand server, and now DB2 refuses to start.

==Symptoms==
When issuing practically any DB2-related command-line utility like db2icrt, or commands inside DB2 like the 'start database manager' or 'activate database archive' as a prerequisite to start Content Manager OnDemand, the process hangs and doesn't return.

==Troubleshooting==
While the DB2 utility or command is still stuck, you can issue the <code> 'ps -ef |grep winbind'</code> command to see if it's consuming a lot of CPU or Memory.

If it is, then stop the winbind service by logging in as root, and issuing the following command:

service winbind stop

If the IBM DB2 utility or command returns, then you need to configure your Linux server to use a Transparent LDAP proxy.

==Solution==

DB2 can be configured with 'Transparent' LDAP: [http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/topic/com.ibm.db2.luw.admin.sec.doc/doc/t0056291.html Configuring Transparent LDAP for Authentication and Group Lookup]

After following the instructions for your specific platform, in the /etc/pam.d/db2 configuration file for your platform, change all references to <code> pam_ldap.so</code> to <code> pam_winbind.so </code>.
