Buddy,
I don't think it is necessarily a problem in 10.1 - just that at this release all the passwords were encrypted so when you rehost a machine you now must re-create your encrypted passwords.
The default adapter is your Windchill DS Administrative LDAP
The enterprise adapter is an external enterprise LDAP - most likely Active Directory, I can't tell you more than that as i don't know your system configuration. If it is one you don't recognise, perhaps you have rehosted the main system before and it is left over from that.
I think we should take this offline now as this is not relevant to the original thread - pm me if you like.
Rgds
Gary
