I think I have worked this out but want ot make sure I have got it correct! Whereas the sync agreement for the FDS <-> AD is from a single FDS server to a single AD domain controller the Passsync facilitiy needs to be installed on all Domain Controllers (am I right?) The reason for this is that the password is hashed before injection into the AD and propagated to other DC's so it is then useless to the Passsync code. The hook therefore needs to be on the DC that receives the password change, which can be any DC in the environment.... A further concern arises with a multi-master FDS and a multiple DC AD. Can the system be set up with multiple FDS <-> AD sync agreements and still allow the results to propagate within the FDS. This would make sense from a fault-tolerant perspective, and off-hand I think the replications should preserve behaviour, but can anybody spot a problem? -- Howard Wilkinson Phone: +44(20)76907075 Coherent Technology Limited Fax: 23 Northampton Square, Mobile: +44(7980)639379 United Kingdom, EC1V 0HL Email: howard at cohtech.com -------------- next part -------------- An HTML attachment was scrubbed...
