RHEV-M LDAP integration Logon VERY slow

Hi,

I added our RHEV-M to our domain so that we can do domain logons... set my id up as administrator, but it takes like 5 minutes for me to logon.

We have a very large AD domain so I guess it is searching the whole thing, just wondered if I can point it to a OU with just the group of RHEV-M admins in it somehow?

Thanks
Bill
