Check if user is a member of an Active Directory Group

[jrhyne2584]

2 things to note.......

a- If you are placing this on a production asp.net server, you will need to provide the LDAP account in the following fashion.....
mydomainblablah\bubbasLDAP_account
The prefixing of the domain is not important on your localhost though.

b- If you need to search nested group memberships, this can really beat up your asp.net server. We recently created an app that copies all the information from active directory into a SQL database. This copying happens automatically everynight.
This method of querying nested group memberships from a SQL database has drastically increased our web applications performance.

Can you reference some resources on how you copied AD to SQL? I'd be interested in pursuing this.
