Hi.
I'm using CentOS 5 with samba3x packages (Samba 3.5.10) and Solaris 10
(Samba 3.5.8) for achieving AD integration. Samba hosts are added as
domain members.
Now, I've tried to add CentOS 6, which also uses 3.5.10, but have
encountered a problem -> users cannot authenticate for some reason.
Configurations are pretty much the same across the board, and they look
like this:
# testparm
Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Processing section "[www]"
Loaded services file OK.
Server role: ROLE_DOMAIN_MEMBER
Press enter to see a dump of your service definitions
[global]
workgroup = DOMAIN
realm = DOMAIN.LOCAL
server string = www2 (Samba ver. %v)
security = ADS
allow trusted domains = No
password server = server.domain.local
log level = 10
syslog = 0
log file = /var/log/samba/log.%m
load printers = No
local master = No
domain master = No
idmap backend = rid:"DOMAIN=10000-49999"
idmap uid = 10000-49999
idmap gid = 10000-49999
winbind use default domain = Yes
cups options = raw
[share]
comment = something
path = /home/share/www
force user = share
force group = share
read only = No
force create mode = 0660
force security mode = 0660
force directory mode = 0770
delete readonly = Yes
Tesparm is ok (exit: 0).

# net ads testjoin -k

wbinfo -u, wbinfo -g, wbinfo -i <username> all work OK... so mapping is ok.
But when I try to access share from other computer, credentials are
refused...
# smbclient \\\\www2\\www -U jakov.sosic

If I take a look at the log, I see this:

Problem is that this exact configuration works OK on both Solaris 10
samba (3.5.8) and CentOS 5 samba3x (3.5.10), but refuses to work on
CentOS 6 samba (3.5.10)...
Any ideas?
