I have a problem with the K2 API.

When I wanted to impersonate the user to get the worklist using .NET form and
Visual Studio , it just stuck there.



This is my code :



 oConn.Open(ConfigurationManager.AppSettingss"K2Server"],
string.Format("{0},{1},{2}",

ConfigurationManager.AppSettingss"CN"],
ConfigurationManager.AppSettingss"username"],

ConfigurationManager.AppSettingss"password"]));

oConn.ImpersonateUser(User.Identity.Name);



The problem is on the second line.

It just stuck there until the web timeout by itself.



When I use the development production , we have no issues there.

This happens when I use the production environment.



The development enviroment using K2 Blackpearl Development License and using
the same build as the production environment.

I recently patch the development environment using the K2 patch K2 blackpearl
4.5 Update (4.10060.1.1420).exe but I didn’t patch the production environment
as the operation is running smoothly without the patch.



This happens yesterday afternoon.

Recently , there is no activity in production environment or changing the
configuration.



We are using Active Directory for the login to the K2 Server

Any solution about this problem?

Thank you
