Manually disabling LDAP authentication
What happened?
You were likely trying to configure Content Manager OnDemand for LDAP, and now OnDemand won't start after enabling the LDAP Authentication checkbox in the OnDemand Administrator Client.
Symptoms and error messages
The documentation for enabling LDAP isn't perfect, and in CMOD version 9.0 and higher, enabling LDAP can cause OnDemand to not start up after issuing the "arssockd -S" command, or refusing to allow logins.
Of course, without being able to start Content Manager OnDemand or being able to log in, you can't turn LDAP off. If you check the OnDemand Library Server's console output, you might find errors like these:
arssockd (ARCHIVE): ARSSOCKD 2 437 ARS0437E The OnDemand stash file >< either does not exist or is not valid. Return Code=4.
If your server does start up, but you can't log in, you'll need to follow these instructions to turn off LDAP authentication, so you can try to figure out what went wrong.
These instructions will manipulate the contents of the CMOD database directly to disable LDAP. USE THESE INSTRUCTIONS WITH CAUTION.
Directions
First, check your system to see what the current value of the SYS_MASK field is:
$ db2 connect to archive
Database Connection Information
Database server = DB2/AIX64 10.1.4
SQL authorization ID = ODADMIN
Local database alias = ARCHIVE
$ db2 "select SYS_MASK from arssys"
SYS_MASK
----------
4
1 record(s) selected.
$ db2 terminate
DB20000I The TERMINATE command completed successfully.
If the result of this query on your system is the same as the example, you can issue the following commands to disable LDAP. If your results are different, skip to the next section.
$ db2 connect to archive
Database Connection Information
Database server = DB2/AIX64 10.1.4
SQL authorization ID = ODADMIN
Local database alias = ARCHIVE
$ db2 "update arssys set sys_mask=0"
DB20000I The SQL command completed successfully.
$ db2 terminate
DB20000I The TERMINATE command completed successfully.
If the results of the query are different on your system, you likely have other options enabled.
$ db2 "select SYS_MASK from arssys"
SYS_MASK
----------
20
1 record(s) selected.
$ db2 terminate
DB20000I The TERMINATE command completed successfully.
In this example, simply subtract 4 from the value returned on your system, and update the field in the database accordingly:
$ db2 connect to archive
Database Connection Information
Database server = DB2/AIX64 10.1.4
SQL authorization ID = ODADMIN
Local database alias = ARCHIVE
$ db2 "update arssys set sys_mask=16"
DB20000I The SQL command completed successfully.
$ db2 terminate
DB20000I The TERMINATE command completed successfully.
If your CMOD server wasn't able to start, try starting it at this point. If your CMOD server was able to start, but you weren't able to log in, stop and start the Library server so the change can take effect.

The root cause of this issue is that you likely do not have a stash file configured for LDAP on CMOD. Here are some IBM Knowledgebase Articles about Content Manager OnDemand stash files and LDAP:
