In 883 and partially in 882ftf2, eDirectory changed the way it handles concurrent connections. Based on requests from NetWare customers moving to OES, e Directory's behavior was changed on non-NetWare platforms to match NetWare behavior. On non-NetWare platforms, concurrent connections was done using a double check method:
(1) Check for network addresses on that entry.
(2) Check for number of connections in dhost connection table for that identity.
On NetWare only step (1) was performed. Also NetWare does not consider port number as part of netware address. To match NetWare behavior a new parameter was added named n4u.server.mask-port-number whose default value is 1 ( i.e behave as NetWare )
Administrator can reset this parameter to 0 and get back to old non-netware platform behavior. Additionally there is a timing window for network address updates. Earlier it used to 5 seconds , in eDirectory 8.7.3 SP10 and 8.8 SP3 it was changed to 15 seconds. This determines the time eDirectory waits before writing a network address to flaim.
