LDAP User Authentication

[CR #431247] Where the LDAP User Authentication (LDAPUA) feature is licensed and configured for HPUX 32-bit and Tru64, and the LDAP servers used for authentification are down or unreachable, then Adaptive Server may temporarily block on network requests to the LDAP server.

The blocking behavior in the Adaptive Server lasts until the configured timeout for the LDAPUA ends. During this time, Adaptive Server is unresponsive and not able to process user requests and activities.

Workaround: Fix the problem that brought the LDAP server down and restart the server.

Sybase recommends reconfiguring a relatively brief timeout value for LDAP User Authentication. For example:

sp_ldapadmin set_timeout, '3000'

This command sets the timeout value used by LDAP User Authentication to 3000 milliseconds or 3 seconds.
