I have a Fedora Linux server, connected to LDAP, and I can't log in to it as my normal user.

I can still log in as root, but even then, I can't create my normal user's home directory. LDAP is configured to auto-mount the user's home directory, but this doesn't seem to be happening. Regretfully, mkdir gives me no useful error message. e.g.

[myuser@localhost ~]# ssh myuser@otherhost Connection closed by otherhost [myuser@localhost ~]# ssh root@otherhost [root@otherhost ~]# cd /home [root@otherhost home]# ls [root@otherhost home]# mkdir myuser mkdir: cannot create directory `myuser': No such file or directory 

What is causing this error?

I suspect something with LDAP has gotten fubared, and that's preventing the directory creation. However, I'm not sure where to begin researching this, as I'm not seeing any useful error messages.

How should I investigate this? Googling for problems creating home directories only gives me a million entries about using mkdir -p, which doesn't help.

EDIT: otherhost:/etc/fstab contains the following line, which defines the mount point for /home:

/dev/mapper/vg_otherhost-lv_home /home ext4 defaults 1 2

Autofs appears to be running.

    How is /home setup? Auto-mounts across NFS? If unsure on the details, the answer ought to be in /etc/auto.* and/or /etc/fstab. Have you talked to whoever originally configured the machine? Commented Jul 26, 2011 at 19:47
  • @andol, Please see my edit. Unfortunately, I no longer have access to the person who originally configured the machine. Commented Jul 26, 2011 at 20:56

Please include the output from vgdisplay -v. If autofs is running (ps -ef | grep automount), please include the contents of /etc/auto.* and the autofs configuration file (usually /etc/default/autofs or /etc/sysconfig/autofs).

EDIT:

It's possible that the line

+auto.master 

in /etc/auto.master is including an auto.master map from LDAP (or NIS) which defines /home as an automounted directory. To be sure, you would have to check the automount entry in /etc/nsswitch.conf and the autofs config file. If nsswitch is defined to go to nis, you would need to run ypcat -k auto.master; if it's defined to go to ldap, you would need to run ldapsearch with the appropriate options for your LDAP server.

To test the theory, just comment out that line from /etc/auto.master and restart autofs.

Automounted directories do not allow you to create new files or directories at the top level, and would give you an error similar to what you are getting if you tried to do so.
