auth_mkhomedir - Autocreate a new account's home directory
#include <courierauth.h> int rc=auth_mkhomedir(struct authinfo *auth);
A callback_func that's passed as a parameter to auth_getuserinfo(3) can invoke this function to automatically create a new account's home directory, if the authlib client is running as root, forwarding the authinfo pointer from the callback. auth_mkhomedir() checks if the AUTH_MKHOMEDIR_SKEL environment variable is set, and if the authenticated account's 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's home directory. If AUTH_MKHOMEDIR_SKEL is not set, or if the home directory exists, auth_mkhomedir() does nothing and returns 0. Otherwise the account's home directory gets created, and the contents of the AUTH_MKHOMEDIR_SKEL directory get recursively copied into the new home directory. The permissions of AUTH_MKHOMEDIR_SKEL and its contents are preserved, and the owner userid and groupid is set to the authenticated account's userid and groupid.
auth_mkhomedir() returns a non-zero value if an error occured while creating the new account's home directory. auth_mkhomedir() returns zero if the new account's home directory was created successfully, or if the account's home directory already exists.
