What version of windows is this ?

When you used to add a uidNumber with the UNIX Attributes tab, the last
uid used was stored in an attribute in AD, this attribute was created
if it didn't exist, has windows stopped doing this ?

The attribute in question is 'msSFU30MaxUidNumber' (there is another
one for groups 'msSFU30MaxGidNumber') and this is stored in the AD
object to be found at:
CN=<Your
lowercase
NETBios
domain
name>,CN=ypservers,CN=ypServ30,CN=RpcServices,CN=System,DC=your,DC=dns,DC=domain
