This does look like a bug, but it only happens if the user is created on one partition and then moved (with "cyradm rename" or similar) to another. If we create users on a partition they get replicated to the equivalent partition on the slave; if we move them on the master, they stay put on the slave though replication seems to continue OK. I'm certainly glad I found this now rather than in production during a restore. This is 2.3.7 derived from Simon Matter's latest SRPM, patched only to customise the ID response. -- Tim Bannister IT Services e: Tim.Bannister@xxxxxxxxxxxxxxxx p: +44 161 2757797 w: http://www.manchester.ac.uk/itservices ---- Cyrus Home Page: http://asg.web.cmu.edu/cyrus Cyrus Wiki/FAQ: http://cyruswiki.andrew.cmu.edu List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
