AIX can be integrated in to Active Directory in two ways: via Samba’s winbind directly as a Windows machine, and indirectly via LDAP. The winbind configuration was already covered in a previous posting and worked rather well. However, because of GE’s requirements, it was not possible to utilize the winbind method for Active Directory integration.
By default, AIX 5.3 has a user name length limitation of 8 characters, regardless of the back end authentication mechanism. To confirm this, run: getconf LOGIN_NAME_MAX or lsattr -El sys0 -a max_logname To set the size limitation to a new (higher) value, run (where # is the new maximum user name length): chdev -l sys0
