Synchronizing Red Hat Directory Server with Microsoft Active Directory Fails if the 'seeAlso' Attribute is Present in a Synced Directory Server Entry

Solution Verified - Updated -


  • Full synchronization with Active Directory fails upon encountering a Directory Server entry with a "seeAlso" attribute


  • Red Hat Enterprise Linux 4

  • Red Hat Enterprise Linux 5

  • Red Hat Directory Server 8.1

  • Microsoft Active Directory
  • Synced user with a seeAlso attribute value set to an entry outside of the synced subtree


  • Resolved in Red Hat Directory Server 8.2

  • If upgrading to Red Hat Directory Server 8.2 is not possible, then the following steps should be followed:

    • Remove the 'seeAlso' attribute from any RHDS entries that have it present
    • Initiate a full re-synchronization with AD
    • Replace the 'seeAlso' attribute to all of the RHDS entries from which it was removed
    • NOTE: Incremental updates with AD will not abort on RHDS entries that have the seeAlso attribute as long as the initial synchronization was completed without this attribute being present
