pam_mkhomedir
PAM_MKHOMEDIR(8) Linux-PAM Manual PAM_MKHOMEDIR(8)
NAME
pam_mkhomedir - PAM module to create users home directory
SYNOPSIS
pam_mkhomedir.so [silent] [umask=mode] [skel=skeldir]
DESCRIPTION
The pam_mkhomedir PAM module will create a users home directory if it does not exist when the session begins. This allows users to be
present in central database (such as NIS, kerberos or LDAP) without using a distributed file system or pre-creating a large number of
directories. The skeleton directory (usually /etc/skel/) is used to copy default files and also sets a umask for the creation.
The new users home directory will not be removed after logout of the user.
OPTIONS
silent
Don't print informative messages.
umask=mask
The user file-creation mask is set to mask. The default value of mask is 0022.
skel=/path/to/skel/directory
Indicate an alternative skel directory to override the default /etc/skel.
MODULE TYPES PROVIDED
Only the session module type is provided.
RETURN VALUES
PAM_BUF_ERR
Memory buffer error.
PAM_CRED_INSUFFICIENT
Insufficient credentials to access authentication data.
PAM_PERM_DENIED
Not enough permissions to create the new directory or read the skel directory.
PAM_USER_UNKNOWN
User not known to the underlying authentication module.
PAM_SUCCESS
Environment variables were set.
FILES
/etc/skel
Default skel directory
EXAMPLES
A sample /etc/pam.d/login file:
auth requisite pam_securetty.so
auth sufficient pam_ldap.so
auth required pam_unix.so
auth required pam_nologin.so
account sufficient pam_ldap.so
account required pam_unix.so
password required pam_unix.so
session required pam_mkhomedir.so skel=/etc/skel/ umask=0022
session required pam_unix.so
session optional pam_lastlog.so
session optional pam_mail.so standard
