NDS authenication via LDAP

P: n/a
Tim
Hello,
I'm trying very (too) hard to log uses LDAP (via ADSI) to autheniticate
users in an A2k2 application. We have AD and I have that working
slick. We are in a tranistion from NDS to AD and I would like to get
the NDS side working during the transition. I know the concept of what
required
Microsoft's information is very sparse and incomplete if not wrong.
1) What would the provider be (and how do we know if I/others have it)
2) What's require in the commandtext (some say LDAP://.. other say
NDS://.. neither work)
3) I'm assuming the context in required with user name but in what
format?
4) What is the ASDI flag?
Keep in mind this code only works on the AD side (txtService = "AD").
This code (with a blank txtService) gives me a "Table does not exist"
error. What table?
