Re: Replacing a default schema for only one instance?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Both files are in the distribution:

/usr/share/dirsrv/schema/10rfc2307.ldif
/usr/share/dirsrv/data/10rfc2307bis.ldif

The primary incompatibility is that the former has 'nisMap' as OID 1.3.6.1.1.1.2.13 and the latter has it as 1.3.6.1.1.1.2.9.
Conveniently, both files have a gap where the other one's OID is, so there is no actual OID conflict with another objectclass. It's just that this one moves, so trying to load both results in two OIDs for the same objectclass.

There are some other differences in syntax declarations and one objectclass (posixGroup) that flips from structural to auxiliary in 2307bis.

For this reasons, other schema file are only used locally and are not automatically transferred to replication partners. Copy the updated schema file manually to the consumers and reload the schema. For details, see Section 12.7, “Dynamically Reloading Schema”.

Hi there,

Are they incompatible because they re-use the same names or OIDS? Would you mind sending a copy of the schema file you plan to use so that I can examine it?

Thanks,
