Bit of background info, we have two domains (DomainA and DomainB) we have two servers (ServerA which is in DomainA and ServerB which is in DomainB both running Domino 6.5). When A user from DomainB tries to login to a database on ServerA using their iPassword its denies them access. However when they try to open the Database on their client machine everything is fine. If I copy the database to ServerB the users can log on using their iPassword. I have created replica of DomainB’s NAB on ServerA called DomainBnames.nsf and vice versa on ServerB but I still can’t get the ServerA to authenticate with DomainB’s NAB. Firstly I hope this makes sense and secondly Is there anyway around this?
