WLC loses user account database after reload

Unanswered Question
Aug 20th, 2008

The certificate on the Wireless Lan controller had expired.

I installed the certificate and restarted the controller.

The controller lost the entire user account database.

I imported the database from another system and after the reload the database was again lost.

Apart from this everything else works fine.

And there are also problems when restoring guest user accounts from Wireless Controll System, WCS the accounts are restored but not the passwords. Also we cannot set expiration date longer then 30 days, we have to set it unlimited first and then change it to limited.

Please let me know if anyone has come across this kind of an issue.

I have this problem too.

I had a similar problem just a day ago:

A WLC4402-50 crashed and lost all of its database entries (Usernames, PSKs, MAC-Adresses,...). I don't know if it restarted and then crashed, or if it crashed and then restarted because of the crash.

The crash log contains this lines:

"Analysis of Failure:

Software was stopped for the following reason:

The system has encountered a fatal condition at mmc_system.c:2093"

Very strange behaviour. I would appreciate any comment, if i have to exchange the hardware or if i shouldn't take any action.
