Hi all
Background: I am not a samba expert, not even close!
I have a ancient samba 3 (Server role: ROLE_DOMAIN_PDC) and I intend to
migrate all files to a samba 4 (Server role: ROLE_DOMAIN_MEMBER)
Users will stay in S3 for now.
Samba 4 joined samba 3 with no problems.
I rsync'ed all files and its permissions (rsync -a ...).
But...
I cannot find a way that makes S4 sees S3 users and groups in a "ordered" manner.
"id some_user" returns "almost" valid data for some users and
"id: ‘some_user’: no such user" for others.
I say "almost" because not all groups for all users are returned.
Example:
S4# id jgarcia
uid=10000(jgarcia) gid=100513(none) \
groups=100513(none),101094(5p6l3d1$),101119(jgomes-pc$),
10001(BUILTIN\users)
jgarcia id should be 101016 (100000 + 1016), and there are missing groups
S3# id jgarcia
uid=1016(jgarcia) gid=1094(jgarcia)\
groups=1094(jgarcia),1000(G00),2009(G01),3011(G02),1119(G03)
For groups is about the same.
for instance:
S4# wbinfo --gid-info 100513
none:x:100513:
S4# wbinfo -G 100513
S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-513
Where did this group "513" come from ?? "Domain Users" ??
If so, why the group name does not come along ??
What smb.conf options should I care so that S4 sees S3 users and groups
like S4[ug]id=S3[ug]id+100000 ??
"idmap config" seams not to be effective.
Is there any options in S3 that I should also change??
How do I make S4 "forget" everything it learned so far about uids and gids from
S3 so I can start fresh??
Cheers
Ethy
