Scenario:
when user will login to ldap server its home directory will change to /home/guests/username

My configurations:

cat /etc/auto.master
/home/guests/ /etc/nfs.auto

cat /etc/nfs.auto
* -fstype=nfs,rw 192.168.1.199:/ldap/&

I am logged in to the machine using xyz[ local user ] username.

When I restart autofs service, it gives me following error

Loaded: loaded (/usr/lib/systemd/system/autofs.service; disabled) Active: active (running) since Mon 2016-02-15 13:25:18 PKT; 16s ago Process: 3962 ExecStart=/usr/sbin/automount $OPTIONS --pid-file /run/autofs.pid (code=exited, status=0/SUCCESS) Main PID: 3964 (automount) CGroup: /system.slice/autofs.service └─3964 /usr/sbin/automount --pid-file /run/autofs.pid

when i su with ldap user , it gives me this error

su: warning: cannot change directory to /home/guests/ldapuser5: No such file or directory

Kindly help me to solve this issue

note:
ldap mount point is working fine with manual mount.

Before you can mount a network file system, the local mount point has to exist.

In other words, you need the system to create an empty directory called "username" under /home/guest whenever a new user logs in. pam_mkhomedir can do just that.
