Hi,

the WCF Service NetSqlAzMan Cache for Windows users wants the user SID and the SID of the groups to which the user belongs.

To do this I have implemented 2 Extension Methods into the namespace NetSqlAzMan.Cache for the WindowsIdentity class.

To obtain this SIDs you can:

1) Use the name (UPN) of the user... (user@mydomain.ext) to create the WindowsIdentity object, using Kerberos protocol Transition:

WindowsIdentity myWinuser = new WindowsIdentity ( "user@mydomain.ext");

 

2) Get the SID using Extension Methods:

using NetSqlAzMan.Cache; / / <= IMPORTANT to see Extension Methods!

...

string userSID = myWinUser.GetUserBinarySSid();

string [] userGroupsSIDs = myWinUser.GetGroupsBinarySSid();

3) Invokes NetSqlAzMan WCF Service Cache passing the above SIDs

Regards,

Andrea.
