Last updated on JANUARY 30, 2023

Applies to:

Information in this document applies to any platform.

Symptoms

DPS fails to create an initial pool of connections to an LDAP data source due to a connection timeout.

The following message will be written in the DPS errors log:

[19/Sep/2012:17:03:40 +0200] - CONN       - WARN  -  Unable to create a connection to LDAP server <HOSTNAME:PORT>/Exception: Unable to perform SSL initialization on socket to <HOSTNAME:PORT> -- java.net.SocketTimeoutException

 

When the DEBUG log level is enabled, the full Java stack will look like:

25/Jun/2012:14:07:29 +0100] - EXCEPTION - DEBUG - Unable to perform SSL initialization on socket to <HOSTNAME:PORT> --
