See:

krb5.conf -> kpasswd_protocol option:

Identifies the protocol to be used when communicating with the server 
indicated by kpasswd_server. By default, this parameter is defined to be 
RPCSEC_GSS, which is the protocol used by Solaris-based administration 
servers. To be able to change a principal's password stored on 
non-Solaris Kerberos server, such as Microsoft Active Directory or MIT 
Kerberos, this value should be SET_CHANGE. This indicates that a 
non-RPC- based protocol is used to communicate the password change 
request to the server in the kpasswd_server entry.
