Hello !



And i have problem with user validation. wbinfo work well, but i cant
use de AD users.

root at samba01:~# smbclient -L 127.0.0.1 -Ugalerna\\gcarballo
Enter GALERNA\gcarballo's password:
session setup failed: NT_STATUS_LOGON_FAILURE

root at samba01:~# smbclient -L 127.0.0.1 -Ugalerna\\administrator
Enter GALERNA\administrator's password:


Administrator work with the mapping root:

root at samba01:~# cat /etc/samba/user.map
!root = GALERNA\Administrator

I use RFC2307 on the provision, but i don't edit anything de uidNumber
& gidNumber.

I change backend to rid and work de validation, but not understand de change.

[global]
security = ADS
workgroup = GALERNA
realm = GALERNA.COM.AR

log file = /var/log/samba/%m.log
log level = 10

idmap config * : backend = tdb
idmap config * : range = 3000-7999
    idmap config GALERNA :backend = rid
     <<<<<-----------
        idmap config GALERNA:schema_mode = rfc2307
        idmap config GALERNA :range = 10000-999999
username map = /etc/samba/user.map

is it okey ? or need to research more?
