You can create a new user, or associate a user that you get from LDAP, and give it the Operator or Deployer role. Then, you can access the Process Center with these users through the normal URL. However, when you attempt to log in with the same users through Process Designer, it does not work.
When you try to log into Process Designer using the normal http://localhost/ProcessAdmin URL, you receive an error message that says: "You are not authorized to use the Process Designer."

The user has not been granted authorization to use the Process Designer.
Resolving the problem
Add the user as a tw_author in the Process Admin Console. This process is described in the Restricting access to the Process Admin Console topic within the information center.
