What OS ?
If it is debian, do you have libpam_krb5 installed ?

Having rfc2307 attributes in AD shouldn't affect the way the 'rid'
backend works.

Did you find it easy to understand ?

Well, No ;-)

there doesn't seem to be anything really wrong, I would use this
smb.conf:

 [global]
   workgroup = CUSTOMER
   security = ADS
   realm = CUSTOMER.LOCAL

   idmap config *:backend = tdb
   idmap config *:range = 3000-7999
   idmap config CUSTOMER:backend = rid
   idmap config CUSTOMER:range = 10000-999999

   winbind use default domain = yes
   winbind refresh tickets = Yes

   vfs objects = acl_xattr
   map acl inherit = Yes
   store dos attributes = Yes

[Shared]
        writeable = yes
        path = /server/shared

[AdminOnly]
        writeable = yes
        path = /server/adminonly

You only need the kerberos lines if you are going to connect to AD with
something like squid.

What packages did you install to make Samba work ?
