Description of problem:
I have freeipa server and client installed. Users on client computers are supposed to login with GDM, even first time, when account just created. But changing password in gdm doesn't work and fails with 'authentication token manipulation error'. I try to change password for existing user using command passwd and it also failed with the same error, kpasswd works fine. Some messages from log fileunsuccesful attempt to change password:

console output from passwd command:
-sh-4.1$ passwd 
Changing password for user dimaktt.
Kerberos 5 Password: 
Warning: Your password will expire in less than one hour.
New password: 
Retype new password:

I've tried to fix problem and looked in source of kpasswd command and pam_krb5:

kpasswd calls krb5_change_password for changing password, pam_krb5-2.3.11-1/src/v5.c contains follwing code:

#ifdef HAVE_KRB5_SET_PASSWORD
int
v5_change_password(krb5_context ctx, krb5_creds *creds, char *password,
                   int *result_code,
                   krb5_data *result_code_string,
                   krb5_data *result_string)
{
        return krb5_set_password(ctx, creds, password, creds->client,
                                 result_code,
                                 result_code_string, result_string);
}
#else
int
v5_change_password(krb5_context ctx, krb5_creds *creds, char *password,
                   int *result_code,
                   krb5_data *result_code_string,
                   krb5_data *result_string)
{
        return krb5_change_password(ctx, creds, password,
                                    result_code,
                                    result_code_string, result_string);
}
#endif

HAVE_KRB5_SET_PASSWORD is defined, so it calls krb5_set_password. I've changed line
#ifdef HAVE_KRB5_SET_PASSWORD
to
#if 0

and built and installed new rpm - and all began to work.


Version-Release number of selected component (if applicable):
pam_krb5-2.3.11-2.fc14.x86_64
ipa-client-1.2.2-6.fc14.x86_64
ipa-server-1.2.2-6.fc14.x86_64


How reproducible:
always


Steps to Reproduce:
1. setup ipa server and client (it can be on the same host)
2. copy /etc/ldap.conf to /etc/nss_ldap.conf (maybe another bug, ipa-client-install configures /etc/ldap.conf, but nss uses /etc/nss_ldap.conf)
3. change pam_sss.so to pam_krb5.so in /etc/pam.d/system-auth (tried also with pam_sss - also doesn't work by default)
4. create user account in ipa and create password for it using ipa-passwd
5. su - to new user
6. try to change password using passwd command
  
Actual results:
passwd command fails


Expected results:
passwd command succesfully changes password
