Description of problem:
We will rebase samba to version 3.6 in RHEL6. Samba 3.6 requires a newer libtdb version which provides a new hashing function. The old hashing algorithm is still supported and the database will not be upgraded to a newer version until the user (e.g. Samba) opens it with a special flag.
Samba 3.6 migrates all tdb's to the new hashing function to fix bugs and improve performance. The new hashing function is magnitudes faster than the old version.
Application which are not aware of the new hashing algorithm will not see any change. They still can simply add a flag to gain the performance boost too.
