PAM is the result of merging two legacy products, Gatekeeper and Password Authority, each having its own database. Some information, for example user information, is stored in both databases. At times PAM performs internal functions that require logging in as "super". The observed messages may indicate that the password is out of sync between the two databases.
This may be observed in any current PAM release.
It should be possible to resolve this issue by setting a new password for super. After you log in as super click the name in the upper right hand corner of the screen, to the left of System Info. It might just say First Name Last Name. Saving the new password will update the super password in both databases. If this does not resolve the problem for you please open a Support ticket.
