CM 23.3 webclient login prompt

Hi,

we were upgrading our CM from CM9.4 to CM23.3. We have done the successful installation along with patch (23.3.100.434) and upgraded schema also successfully. But the webclient and service api keep asking for login after entered correct user name and password. we are using windows authentication.

i saw this issue while using RM initially. Any idea how to fix this..

Thanks,

Sarath.
