ANR3114E LDAP error 81. Failure to connect to the LDAP server

Posted by xaminmo

This used to be on IBM’s website, but it disappeared.  It is referenced all over the net, and needed to still exist. I only found it in the wayback machine, so I’m adding another copy to the internet.

2013 SOURCE: www-01.ibm.com/support/docview.wss?uid=swg21656339

Problem(Abstract)

When the SET LDAPUSER command is used, the connection can fail with:

ANR3114E LDAP error 81 (Can’t contact LDAP server)

Cause

The user common name (CN) in the SET LDAPUSER command contains a space or the ldapurl option is incorrectly specified.

Diagnosing the problem

Collect a trace of the Tivoli Storage Manager Server using the following trace classes:
session verbdetail ldap ldapcache unicode

More information about tracing the server can be found here: Enabling a trace for the server or storage agent

The following errors are reported within the trace:

Resolving the problem

  • In the trace provided, the common name (CN) contains a space. (CN=tsm user,OU=TSM,DC=ds,DC=example,DC=com)

    Remove the space in the common name when using the SET LDAPUSER command. For example:

    SET LDAPUSER “CN=tsmuser,OU=TSM,DC=ds,DC=example,DC=com”

  • Use an LDAP connection utility such as ldp.exe to ensure the ldapurl option is correct and the LDAP server is accepting connections

    <ldapurl> port 636, check the box for SSL

    Verify there are no errors in the output
