AD(7) Standards, Environments, and Macros AD(7)

ad - Active Directory as a naming repository

Solaris clients can obtain naming information from Active Directory (AD) servers.

The Solaris system must first join an AD domain and then add the ad keyword to the appropriate entries in the nsswitch.conf(5) file. The Solaris system joins the AD domain by using the kclient(8) utility. The AD name service only supports the naming databases for passwd and group.

Windows users are not able to log in. The user_attr(5) database has no entries for Windows users, and the passwd(1) command does not support the synchronization of user passwords with AD.

The Solaris AD client uses auto-discovery techniques to find AD directory servers, such as domain controllers and global catalog servers. The client also uses the LDAP v3 protocol to access naming information from AD servers. The AD server schema requires no modification because the AD client works with native AD schema. The Solaris AD client uses the idmap(8) service to map between Windows security identifiers (SIDs) and Solaris user identifiers (UIDs) and group identifiers (GIDs). User names and group names are taken from the sAMAccountName attribute of the AD user and group objects and then tagged with the domain where the objects reside. The domain name is separated from the user name or group name by the @ character.

The client uses the SASL/GSSAPI/KRB5 security model. The kclient utility is used to join the client to AD. During the join operation, kclient configures Kerberos v5 on the client. See kclient(8).
