.SH "NAME"
auth_mkhomedir \- Autocreate a new account\*(Aqs home directory
.SH "SYNOPSIS"
.sp
.nf
#include <courierauth\&.h>
.fi
.HP \w'int\ rc=auth_mkhomedir('u
.BI "int rc=auth_mkhomedir(struct\ authinfo\ *" "auth" ");"
.SH "DESCRIPTION"
.PP
A
\fIcallback_func\fR
that\*(Aqs passed as a parameter to
\m[blue]\fB\fBauth_getuserinfo_meta\fR(3)\fR\m[]\&\s-2\u[1]\d\s+2
can invoke this function to automatically create a new account\*(Aqs home directory, if the authlib client is running as root, forwarding the
authinfo
pointer from the callback\&.
.PP
\fBauth_mkhomedir\fR() checks if the
\fBAUTH_MKHOMEDIR_SKEL\fR
environment variable is set, and if the authenticated account\*(Aqs home directory does not exist\&. If the environment variable is set it must point to a directory like
/etc/skel
that contains a template for the contents of a new account\*(Aqs home directory\&.
.PP
If
\fBAUTH_MKHOMEDIR_SKEL\fR
is not set, or if the home directory exists,
\fBauth_mkhomedir\fR() does nothing and returns 0\&. Otherwise the account\*(Aqs home directory gets created, and the contents of the
\fBAUTH_MKHOMEDIR_SKEL\fR
directory get recursively copied into the new home directory\&. The permissions of
\fBAUTH_MKHOMEDIR_SKEL\fR
and its contents are preserved, and the owner userid and groupid is set to the authenticated account\*(Aqs userid and groupid\&.
.SH "RETURNS"
.PP
\fBauth_mkhomedir\fR() returns a non\-zero value if an error occured while creating the new account\*(Aqs home directory\&.
\fBauth_mkhomedir\fR() returns zero if the new account\*(Aqs home directory was created successfully, or if the account\*(Aqs home directory already exists\&.
