Hi folks,
During migration existing Kerberos/LDAP setup clients to IPA, after
'ipa-client-install' command is run and reports successful migration, we found
that the client fails to talk with IPA server.
The symptom is: in the /var/log/messages file at IPA client side, we can see
the following entries:
Apr 30 11:07:04 ldapclient02 sssd: Starting up
Apr 30 11:07:05 ldapclient02 sssd[be[pegaclouds.com]]: Starting up
Apr 30 11:07:06 ldapclient02 sssd[pam]: Starting up
Apr 30 11:07:06 ldapclient02 sssd[nss]: Starting up
Apr 30 11:07:06 ldapclient02 [sssd[ldap_child[2133]]]: Failed to
initialize credentials using keytab [(null)]: Decrypt integrity check failed.
Unable to create GSSAPI-encrypted LDAP connection.
It is figured out that, instead of backup and overwrite /etc/krb5.keytab,
ipa-client-install only appends the new generated host keytab entries to the
same file /etc/krb5.keytab. Then when the original entries have a higher KVNO
version than the newly generated siblings, the latter is shadowed and ignored.
After manual removing the old entries from /etc/krb5.keytab with the tool
ktutil (rkt, delent, wkt), the client immdiately connects to IPA server and
problem goes away. It will be greatly appreciated if native ipa-rmkeytab can be
extended to do the same job.
Thanks.
