Description of problem: When logging in using Kerberos, module pam_krb5.so seems to validate the TGT using system Kerberos database (/etc/krb5.ketab). It usually ends up using the "host/" principal for this checks. This check works fine unless there are more "host/" principals in the system keytab file (for example some process is renewing them creating new principals with a higher KVNO) - in this case, pam_krb5.so seems to pick the first one only and the check will fail with the message like this: pam_krb5[27045]: TGT failed verification using keytab and key for 'host/draco.prague.s3group.com.S3GROUP.COM': Wrong principal in request and the user login attempt is rejected. Version-Release number of selected component (if applicable): pam_krb5-2.3.11 How reproducible: always
