I am starting to run into a major problem with Config Server 5.1.51x that is really bothering me.
From time to time, depending on the config file, I was able to literally mess up the security definitions in CME. After booting the config server, if I would open an application and click on Securities/Permission then SOMETIMES I would see all the access groups in DUPLICATE. If I would try to add or remove an access group, it would tell me that I do not have enough access rights to do so, even though I was logged in as default! 
I am enclosing a confserv.conf file that causes it.
PLEASE, DO NOT USE IT ON EXISTING CME DATABASE, BECAUSE I AM NOT SURE IF IT IS MESSING UP THE DATABASE OR NOT!

I cannot duplicate the problem ALL the time…
