Re: DNA plugin not working

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

 



Hi Thierry,

The thing is, while this is on the production multi-master cluster, it’s not being used yet.  Any new entries being added have uidNumber set explicitly, except for my test entry.  I’ve been trying a few things and have a different error message now but the same result.  I’ll update the thread shortly with further details.

Best regards,

James
