Realms on IDM 2.3

[Stephan Lache]

Hello,

i have some trouble regarding realms.
it´s strange that i have 2 realms.
one with the netbois name of my active directory domain and on with the dns name
( AD synchronisation is activated)
when i delete the "netbios realm" it is autodiscovered again.

i read about the issue with the different logons. domain\user vs. user@domain
i am quite sure that no user is logging on with domain\user.
has anybody a idea how i can get rid off the netbios realm ?

thanks in advance

stephan
