GAL MA errors "The LDAP Server is unavailable" and "It appears this forest is not Exchange enabled" RRS feed

  • General discussion

  • I recently tried to set up the GAL management agent in a Windows 2008 / Exchange 2010 environment and got some strange errors while configuring the GAL MA.


    Though I fulfilled all prerequisites to support Exchange 2010 GAL syncs

    • PowerShell 2.0 installed on the ILM server
    • ILM 2007 SP1 FP1 built 3.3.1139.2

    I got LDAP server connectivity errors which results that the GAL MA could not detect the Exchange version of the Active Directory forest.

    This was strange the more, because i could successfully connect to the forest in the “Connect to Active Directory Forest” section of the GAL MA configuration.


    It turned out that the MA has a problem with the format of the credentials I submitted. I could overstep the errors, when providing account credentials in the UPN format.


    I found some threats in the FIM2010 forum, which resolved the issue with Update1 for FIM2010. Due to the fact that I couldn’t find any update for ILM 2007 available I found it valuable to share my experiences

  • I had the exact same problem. When I installed ILM of the ISO the build was This did not experiance this issue. Build does not support Exchange 2010, only 2007!

    When I upgraded the build to 3.3.1139.2 by installing KB977791 the issue occured.

    Unfortuantly this did not resolve my problem.
