I am running ZCM v11.2.1.0 on a SUSE Linux Enterprise Server v10. All my Windows 7 clients have ZCM agent v11.2.1.0. We added an Active directory user source. The user source works fine if I have the windows client's ZCM agent login specifically to the AD user realm. However the settings I have in place to default to the AD user realm are not being respected by the ZCM agent on the Windows 7 machines. The exact problem I'm having is described in the following thread:

Support | ZCM agent with nwclient ignores DefaultRealm configuration when multiple realms are configured

Does anyone know of a way around this problem or if "Engineering" has fixed the problem?
