Does anyone know whether it is possible to use .Net Passports as a
method of Authentication / Authorization to the Active Directory and
SharePoint Portal.

Accessing the SPRoleCollection requires Administrator right or at least Manage Site Groups right.

The only way around it that we found is to issue a web service call impersonating the user as an administrator.

Additional question: Where could I have found the information that I needed the administrator rights for accessing the SPRoleCollection

Answer #3    Answered By: George Watson     Answered On: Nov 07

Here is the problem, I couldn’t find documentation about the security role for SPRoleCollection. I just concluded that this was an issue

Below is a code snippet for a VB.NET function. This function refers to a Web Service myws that references /_vti_bin/UserGroup.asmx and it returnes an array containing the list of roles the user belong to.

Please note that I am storing the username/password/domain of a user with sufficient admin right in the web.config file.
