In the custom UI under Admin - Security. We also import the users in the AD group instead of creating manually.
Custom UI > security as TD suggested. Configure a LDAP host, enable auto-sync, and a populate a LDAP group for the vCOps group(s) in focus.
One other thing: we have several AD groups for different access levels, so we greated a separate OU that we use as the base dn in the LDAP host defintion. That way, when we import, only the groups that we want are imported. You might have multiple OU entries, depending on how your AD is configured.
