Symptoms

In some circumstances LDAP may fail to setup StartTLS on the server-side when instructed by a LDAP client when the LDAP virtual server is in use with a persistence profile.

Impact

Serverside does not upgrade to TLS.

Conditions

- LDAP virtual server with client and server profiles. - LDAP profiles with STARTTLS Activation Mode set to Allow. - Persistence profile (for example, src addr persistence).

Workaround

Do not use LDAP virtual server in conjunction with persistence.

Fix Information

The BIG-IP system now correctly upgrades the serverside connection of a LDAP virtual server to TLS.
