Cause

This error occurs when a filter request is made to the LDAP server with bad syntax.

Example of filter with bad syntax:

Group Object Filter = (objectCategory=Group)(cn=hipchat)
The correct filter should be:


Group Object Filter = (&(objectCategory=Group)(cn=hipchat))


Resolution

  1. Edit your LDAP directory configuration within Hipchat Server
  2. Check your filter configurations for both the Users Schema and Groups Schema

Description

This page covers how to resolve a failing LDAP synchronization issue with the Hipchat Server.
