  • 1.  LDAP Auth => Aruba650 w/6.1.3.8 to MS 2008R2

    Greetings, I realize that there have probably been a thousand threads on this. Having problems getting Aruba 650 controller to do LDAP auth against a Microsoft 2008R2 AD environment. Keep getting error as follows:

     

    " authmgr[1580]: <199802> |authmgr| ldapclient.c, ldap_auth_api:124: Invalid authentication protocol 4 for LDAP"

     

    Any help would be greatly appreciated.

    Is this for captive portal authentication?

     

    Change your authentication type to PAP under the Captive Portal Authentication Profile.

    At this point, just trying to get the server provision under Authentication / Servers / LDAP and then tested under Diagnostics.

     

    UPDATE!!!! -- Got it!  -- I had the base DN incorrect.  When I brought it up a level and issued the query user command as referenced in the article you posted, it worked.  Validated I was using the wrong OU for the test user.  Once fixed, works like a champ!

     

    THANKS!
