Hi, thank you for you reply
I try to use Kerberos to authenticate some services support it.
I want to use Kerberos for authentication and LDAP for authorization in my system.
At current step I can allow users to login using LDAP, and users must get a ticket to use
some LDAP's tools.
And as you see, I'm confused a bit. That system have two passwords for an user and they
just can change one of them. Two passwords can be used to login.

What does that mean? Is your KDC using OpenLDAP as backend-database or
are you just using Kerberos tickets to authenticate against the LDAP
server with SASL GSSAPI bind?

This is related to your PAM configuration.

Ciao, Michael.
