KB-3433: What are the methods to disable SSO for users?

Centrify DirectControl ,

Applies to: All versions of Centrify DirectControl

 

Question:

What are the methods to disable Single-Sign On/Kerberos for AD users?

 

Answer:

GSSAPI is the authentication method that is used for single sign on (SSO).

 

If GSSAPIauthentication is disabled, the user will still be able to login by using PAM - but SSO will no longer work.

 

There are two methods to disable SSO:

 

Option 1: Client side

 

  • In PuTTY go to:

    Connection -> SSH -> Auth -> "Attempt GSSAPI/SSPI auth (SSH-2)" -> Disable this option

     
  • Or:

    Connection -> SSH -> Auth -> GSSAPI -> "Allow GSSAPI Authentication (SSH-2 only)" -> Disable this option

 

 

Option 2: Server side

 

  • vi into /etc/centrifydc/ssh/sshd_config
     
  • Uncomment the following parameters and save the file.

    GSSAPIAuthentication no
    GSSAPIKeyExchange no

     
  • Run adreload and restart the Centify sshd server
