The pam_oddjob_mkhomedir.so module checks if the user's home directory exists, and if it does not, it
invokes the mkhomedirfor method of the com.redhat.oddjob_mkhomedir service for the PAM_USER if the module
is running with superuser privileges. Otherwise, it invokes the mkmyhomedir method.
The location of the skeleton directory and the default umask are determined by the values of HOME_MODE or
UMASK (as a fallback) variables in /etc/login.defs, so they can not be specified as arguments to this
module.
If D-Bus has not been configured to allow the calling application to invoke these methods provided as
part of the com.redhat.oddjob_mkhomedir interface of the / object provided by the
com.redhat.oddjob_mkhomedir service, then oddjobd will not receive the request and an error will be
returned by D-Bus.
If oddjobd has not been configured to provide these methods, or the user is not authorized to use them,
then oddjobd will ignore the module's requests.
