PAM_MKHOMEDIR(8) Linux-PAM Manual PAM_MKHOMEDIR(8)
pam_mkhomedir - PAM module to create users home directory
pam_mkhomedir.so [silent] [debug] [umask=mode] [skel=skeldir]
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.
silent
Don't print informative messages.
debug
Turns on debugging via syslog(3).
umask=mask
The file mode creation mask is set to mask. The default value
of mask is 0022. If this option is not specified, then the
permissions of created user home directory is set to the value
of HOME_MODE configuration item from /etc/login.defs. If there
is no such configuration item then the value is computed from
the value of UMASK in the same file. If there is no such
configuration option either the default value of 0755 is used
for the mode.
skel=/path/to/skel/directory
Indicate an alternative skel directory to override the default
/etc/skel.
Only the session module type is provided.
