How to retrieve user credentials in .Net?

Asked by davewalter1 in .Net Editors & IDEs, .NET, Microsoft Visual Basic.Net

Tags: VB.Net, Firefox, IE, "No mapping between account names and security IDs was done. (Exception from HRESULT: 0x80070534)"

I posted this question and received a clue here: http://www.experts-exchange.com/Microsoft/Development/.NET/Q_23064765.html

I need to retrieve the credentials of a logged-in user from our LDAP server. The clue I've received is to use System.Net.CredentialCache. Does the browser cache hold the same user information as in that user's LDAP record? Is there a list of attribute names, such as UserName, CountryCode, etc. somewhere that would show me what information is available?  I don't know how to employ this.

The test code that I'm working with is below, and fails with the error: "No mapping between account names and security IDs was done. (Exception from HRESULT: 0x80070534)."  If I can get my test to work, I'm sure I'll be able to use this in the rest of my application, but I'm self-taught and not good enough with ASP.Net to be able to fix this code myself.
