On AIX when there is an entry in a user-map file pointing to Unix enabled AD user but no local user to map in the /etc/passwd file the following error is seen on login:
Could not chdir to home directory /home/jdoe: A file or directory in the path name does not exist.
Steps to reproduce:
1. AIX 7.1
2. auth_type = STD_AUTH
3. User map file
4. Local user does not exist (never has),
5. No home directory for the AD user
6. Login as the AD user
Works in Linux, doesn't work on AIX.
