• Kerberos is a computer network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. (Reference taken from Wikipedia.com).
• Generic Security Service Application Program Interface (GSSAPI) is an IETF standard for doing strong encrypted authentication in network based applications. OpenSSH uses this API and the underlying Kerberos 5 code to provide an alternative means of authentication other than ssh_keys. (Information taken from Using GSSAPI authentication at SLAC).

Disable Kerberos and/or GSSAPI

Disable Kerberos and or GSSAPI by editing /etc/ssh/sshd_config.

1. Login as root.
2. Open /etc/ssh/sshd_config in a text editor and and modify the following entries:
   1. ​Under Kerberos options, modify any entry that is uncommented and set to yes to no. For example,

# Kerberos options
KerberosAuthentication yes

# Kerberos options
KerberosAuthentication no

2. Under GSSAPI options, set GSSAPIAuthentication and GSSAPICleanupCredentials to no. For example,

# GSSAPI options
GSSAPIAuthentication no 
GSSAPICleanupCredentials no

3. Save the file and restart sshd using the following command:

​# service sshd restart
