On one of our NW6.5 SP4a server consoles, we keep getting the following
error:

NMAS Intruder Detection Locked User Account
CN=xxxxxxxx.OU=xxxxx.O=xxxxx..

This keeps happening to 2 of our Network Administrators and if you
check ConsoleOne, their account is truly locked.

We cannot find any information on what causes this or how to fix it -
any help is appreciated.

TIA
