[Samba] attributeID is not known in our schema, not fixing replPropertyMetaData

[Karan Blas]

I expected that someone had the same problem before.

DBchecker module does not provide fix for this. The implication is that the main Samba DC is working fine but does not allow replication with other DCs. They report WERR_DS_DRA_INTERNAL_ERROR in samba-tool dsr showrepl for two two sections: Configuration and the main one that contains the users. Other sections replicate fine.

Promoting new DC also does not work. Data (both new and old) are locked in this single DC 4.2.14. Exporting the database and importing it in 4.6.3 fix some things but not this one.

We found that replPropertyMetaData is uniquie for each user, setting it empty "fix the error' but breaks the user object.

How to recreate this attribute properly? How to remove all entries about attributeId 0XB7D8382? It was inherited from Exchange.
