The system log on my Openfire + OpenLDAP installation is getting flooded with this message:
slap_global_control: unrecognized control: 1.2.840.113522.214.171.1243
This means that Openfire wants OpenLDAP to do server-side sorting, which OpenLDAP doesn't support. The Openfire LDAP Guide advises to set the property ldap.clientSideSorting to true in this case.
Unfortunately, Openfire doesn't find any user accounts in LDAP anymore if I do that. How do I make this work?
