3. Active Directory
In recent months, we have become aware of potential issues with Microsoft Active Directory which can only be resolved by creating an A record in the DNS for the domain name, to be pointed at one or more of the Active Directory servers, and one has now been added for one unit.
Even though Active Directory makes widespread use of SRV records, it appears that in certain setups they are ignored by clients and an A record for the domain name may be required. At present there is no Active Directory realm named ox.ac.uk but it is possible that one may be required as part of (or an extension of) the Groupware Project. A decision at this stage to support http://ox.ac.uk/ therefore has clear implications regarding the future possibility of such a central Active Directory service (recall that using ox.ac.uk for one service is at the exclusion of all others).
