When I try to login into macosx i got this error:

"You cannot continue loggin in at this time.
There is a problem that prevents you from loggin in at this time.
please contact your system administrator for help."

After saying "ok" I can login into macosx and work regularly...

What can I do for preventing the warning message?

Thanks in advance
