    Hi all,

     

    I'm trying to join Policy Manager to an AD domain but I receive this error

     

    kinit succeeded but ads_sasl_spnego_gensec_bind(KRB5) failed for
    ldap/tdcesol.local with user[Administrator] realm[TDCESOL.LOCAL]: Unexpected information received
    Failed to join domain: failed to connect to AD: Unexpected
    information received

     

    Any idea what could it be happening?

     

    Thanks!

     

    Regards,

    Jorge

    Solved. Problems with Domain Controller name! ;)

    Same Here. Thanks!

    I changed the Computer name to match my DNS entry, but I assume you could change the DNS entry to match the computer name on your Domain Controller.

     

    Example:

    My Domain Controller computer name was ad01.aruba-lab which did not work because my DNS entry was just ad01.arubalab.net

    The Join failed when those 2 did not match.  Since this is a lab unit, I change the DC's computer name to just ad01 and it worked.

     

    My thought is that I could have also changed the DNS entry to ad01.aruba-lab.arubalab.net if changing the computer name was not possible.  I did not test this though.
