LDAP Connection - Internal Error : Invalid response (-1)

  • 1.  LDAP Connection - Internal Error : Invalid response (-1)

    Posted Apr 18, 2012 12:01 PM

    Hi,

    I tried the last few hours to connect our Aruba 3200 Appliance (ArubaOS 6.1.2.3) to our MS w2k8 Active Directory by using LDAP but it doesn`t work. When I use the "AAA Test Server" I get the message: 'Internal Error : Invalid response (-1)'

     

    I use these settings:

     

    Admin-DN: CN=Admin,OU=Users,DC=campus,DC=local

    Base-DN: OU=teacher,OU=school,DC=campus,DC=local

    Filter: (objectclass=person)

    Key Attribute: sAMAccountName

     

    I have no idea why this doesn't work or what's wrong with the configuration or the response. Other Systems are using an LDAP connection to our Active Directory as well. Has anyone an idea what could been the problem?
    Regards,
    Alex

    Is the admin password correct?

    Hi,

    we tried the users "Admin" and "Administrator" and we got the same message. When I try to connect to another Active Directory, the same problem appeared.

    Hi Alex,

    This may help ;

    Yesterday I was doing same Ldap integration .

    I have selected  1. Preferred connection Type = clear-text   and checked the box  "allow clear -text" .   under Servers > LDAP Server in controller.

    I got the same error when I tried  to check  the authentication from  Controller > dignostics > aaa server test  then I noticed the method selected was MS-CHAP-v2   for this setup PAP is required . after selecting PAP the authentication was successful.

    Hate commenting on a thread that is just over a year old.  Here we go.

     

    I am having the same issues as above.  I had to change my Termination Inner EAP-Type to eap-gtc in order to get iOS devices to authenticate. However now it seems that now my Windows clients are unable to authenticate.  

     

    When I switch the inner eap-type back back eap-mschapv2 neither can connect using 802.1x.

     

    EDIT:  Nevermind, found my answer here... SHIM!
