Comment 2 Jakub Hrozek 2016-11-28 14:23:31 UTC

This seems to be more of an sssd issue so I'm 'stealing' the bug.

Comment 3 Sumit Bose 2016-11-28 15:10:11 UTC

It looks like it is related to 'krb5_use_enterprise_principal = True' or the automatic setting of it in the 7.3 version of SSSD.

If the enterprise principal feature is not needed for the AD users the setting 'krb5_use_enterprise_principal = False' in the [domain/...] section of sssd.conf would be a work-around.

Comment 4 Sumit Bose 2016-11-28 15:33:26 UTC

To reproduce this outside of SSSD you can call

    KRB5_TRACE=/dev/stdout kinit -E -C ipauser -S 'kadmin/changepw'

Assigning to krb5 to get feedback what it the expected behavior here, i.e. requesting 'kadmin/changepw' ticket to change an expired password with an enterprise principal.
