.SH "NAME"
pam_mkhomedir \- PAM module to create users home directory
.SH "SYNOPSIS"
.HP \w'\fBpam_mkhomedir\&.so\fR\ 'u
\fBpam_mkhomedir\&.so\fR [silent] [umask=\fImode\fR] [skel=\fIskeldir\fR]
.SH "DESCRIPTION"
.PP
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\&.
.PP
The new users home directory will not be removed after logout of the user\&.
