IDMU

Microsoft offers a feature called Identity Management for UNIX (IDMU). This software is available for Windows Server 2003, and is bundled with Windows Server 2003 R2 and later. This feature is part of what was formerly called Services for UNIX in its unbundled form.

The primary use of IDMU is to support Windows as a NIS/NFS server. IDMU lets the administrator specify a number of UNIX-related parameters: UID, GID, login shell, home directory, and similar for groups. These parameters are made available using AD through a schema similar to but not the same as RFC2307, and through the NIS service.

When the IDMU mapping mode is used, the identity mapping service uses these UNIX attributes to establish mappings between Windows and UNIX identities. This approach is very similar to directory-based mapping, except the identity mapping service queries the property schema established by the IDMU software instead of allowing a custom schema. When this approach is used, no other directory-based mapping can be used.
