[Samba] bad home path from AD

[Arnaud Bougeard]

Hello

I think I have a mapping problem.

The server was added to the domain with sudo net ads join -U 
adj-compo at ur.local

The server is also connected to an LDAP server via SSD

When loading the user's homes, the server does not look for the correct 
homedir path which should be /private/student/7/17/tdsi917 for the user 
tdsi917

Here are the values and variables retrieved by the 3 commands:

# getent passwd ur\\tdsi917
tdsi917:*:16945606:16977729::/home/UR/tdsi917:/bin/false

# getent passwd tdsi917
tdsi917:*:122025:99999:test 
dsi917:/private/student/7/17/tdsi917:/usr/local/bin/ur1shell

# id tdsi917
uid=122025(tdsi917) gid=99999 
groupes=99999,16945606(tdsi917),16977729(domain 
users),17138962($ijv700-jaannteirkd3),17169934($ert800-5ggunedtuc7k),17121891($3ue700-90qmsldqmphu),16975181($da1600-8q4gb3joj2c9),17156453($5mg800-qp8djjrmdrod),17155068($saf800-r89h2bc6j7a6),17098681($p8o600-b3lnss0ku69r),17098673($h8o600-asepe2uhj93k),17121890($2ue700-3vk366s8s8nf),17169935($frt800-8l9h6ago3m6l),17131976($8po700-dj95nr2nh69g),17138960($gjv700-3rcp24o2rlvs),17131837($tko700-b5g5n6ti3aor),17138961($hjv700-5pebr12ui2pt),16974329($pf0600-svtpf15svlnj),17144064($0j4800-12qqqai06tc5),16966428($soo500-kso5c5o4qd6c),17169933($drt800-91fnd965nvcg),17169365($l9t800-1i3jm4qpr31r),16777217(BUILTIN\users)

Here is the extract from the samba logs for a client connection :
