Atomic RID allocation in LDAP

Our implementation updates the nextRid attribute in the
domain entry (eg. dc=windows,dc=samba,dc=org) whenever a
RID needs to be allocated. Removing the old value and
adding the new one is used to guarantee atomicity.

It is interesting to note that the distributed RID
allocation scheme used in Active Directory is patented
by Microsoft. This is only useful in a multi-master
directory, though.
