OEL 6.1: Winbind authentication fails to create homedirs

Question

Dear all,
I have an OEL 6.1 server where I need users to authenticate using samba/winbind. I deployed the configuration 1 of the choices given in the relevant manual "Integrating Red Hat Enterprise Linux 6 with Active Directory" (http://jp.redhat.com/rhecm/rest-rhecm/jcr/repository/collaboration/jcr:system/jcr:versionStorage/23549efa0a0526020ce2917… ).
The problem is that although I have authentication, then the user's home directory is not created automatically (although I've checked the relevant box in the authentication configuration tool):
When I ssh on the server I get the message "Could not chdir to home directory /home/%D/%U: No such file or directory".
Can you help me identify the problem?
Best,
Nikos

Answer 1

I had the following line (1):
session     optional      pam_oddjob_mkhomedir.so
I replaced it in both files /etc/pam.d/system-auth and /etc/pam.d/password-auth with the one Dude proposed, line (2):
session     required      pam_mkhomedir.so umask=0022 skel=/etc/skel
and now the system creates the home directories.
However I have a question. As this is the second server I setup, the first one works fine with the line (1). The second server now uses line (2). Line (1) is the one auto-written by the authconfig tool. So, if I use the authconfig tool again these files will again change and I will have to manually change this line again. Is this normal?
Cheers,
Nikos
