Attempting to change another user’s password with a program such as passwd or cl_chpasswd does not work when logged on to an AIX computer as an Active Directory user.
Cause:
Missing or incorrect setting for the AUTHSTATE environment variable.
Resolution:
Set the AUTHSTATE environment variable to compat before attempting to change another user’s password with a program such as passwd or cl_chpasswd. For example, if you are using the ksh shell and the cl_chpasswd program to change another user’s password, you would enter:
$ AUTHSTATE=compat cl_chpasswd
Note: You do not need to modify the AUTHSTATE environment variable to change your own password.
