Unable to logon to Web Dynpro Content Administartor

Hi,

I'm having a problem where I am unable to logon to the Webdynpro Content Administartor. I am using the J2EE_ADMIN user.

When I enter the password nothing happens.

If I enter the wrong password I get the following error "user authentication failed". I am able to logon to the visual administrator and sld with the same user id and password.

It is not locked.

I have also tried activating the SAP* user, but this has the same problem.

Any ideas?

Regards

Andy
