Plugin error: SecWinAD Error: invalid parameters in ParseUserInfo

39 Views

Hi all, I'm trying to set up a .Net web-application running on IIS7 which connects to a XI2 server via the .Net SDK for AD single-sign on, and I'm getting a strange error on some of our servers. By that I mean that some web-servers with a seemingly identical setup (i.e. the same web-app and server config) work whilst others don't. Our setup:

1. Site in IIS is set to Windows Authentication, Anonymous Access disabled

2. ASP.Net impersonation is set to true

3. .Net code calls SessionMgr.Logon with an empty username + password

On the servers that this fails on, we get the generic error (all servers connect to the same XI2 server):

"The Active Directory Authentication plugin could not authenticate at this time. Please try again. If the problem persists, please contact your technical support department."

But I used Wireshark (a packet sniffing tool) to see if there was anything else in the data being transfered from our web-server to the XI2 server. The full error is actually this:

"Plugin error: SecWinAD Error: invalid parameters in ParseUserInfo"

Does anyone have any idea what this error means?
