[SSSD-users] Home Directory not being created

I'm having a problem getting pam_mkhomedir.so to make a user's home directory when it's specified using an LDAP attribute. The backend directory server is AD on Server 2008. The client is Ubuntu 12.04, sssd version 1.11.1. First, my sssd.conf: [sssd] config_file_version = 2 debug_level = 0 reconnection_retries = 3 sbus_timeout = 30 services = nss, pam domains = domain [pam] debug_level = 0 [nss] debug_level = 0 filter_users = root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman,nscd,gdm filter_groups = root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman,nscd,gdm reconnection_retries = 3 [domain/domain] debug_level = 0 ad_domain = domain.local id_provider = ad auth_provider = ad chpass_provider = ad access_provider = ad enumerate = true cache_credentials = true # Will check unixHomeDirectory LDAP attribute for a value first fallback_homedir = /home/%u ldap_user_home_directory = unixHomeDirectory dyndns_update = true dyndns_update_ptr = true ldap_schema = ad ldap_id_mapping = true I'm testing using the Guest user. Guest, unlike all my other users, has a home directory set in the unixHomeDirectory attribute (/tmp/Guest). All other users rely on the fallback_homedir option. When a normal user signs in and does not have a home directory, I've configured pam to create one by adding this to the common-session file: session required pam_mkhomedir.so umask=077 This all works fine when ldap_user_home_directory is empty; the home directory is created automatically upon logging in using the fallback_homedir option. However, when unixHomeDirectory actually contains a path, no home directory is ever created and I'm always dropped in /. Interestingly enough, "echo $HOME" as the Guest returns two different values depending on if fallback_homedir is set. If it is set, $HOME = /home/Guest. If it's commented out, $HOME = /tmp/Guest. Any ideas? Thanks! -Chris
