Why is Kerberos and LDAP LDAP is very effective for storing and retrieving user attributes for AIX users, but using LDAP for authentication still requires the user to provide an AIX password and an AD password. Kerberos supports AIX using the local AD protocol to authenticate users by referencing their Microsoft Windows passwords. Active Directory Properties for use The following AD properties can be use

In this way, the system automatically creates the standme directory, then you are prompted to set the password. If useradd is used, passwd user is also required to set the password. Previously, w
