pam_succeed_if(sfcb:auth): error retrieving information about user

Hi,

while trying to find a hint for a differnt problem I discovered tons of messages like this one in syslog.log

sfcb-CIMXML-Processor[45596]: pam_succeed_if(sfcb:auth): error retrieving information about user xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

Does someone have clue where this might come from? Or how I can find it out?

Thanks

Robert
