I have added the default (ACME.XML) and a customized (say, abc.xml) organization on to the portal. I don't know but I think something is getting messed up and only some of the users can login. For eg; walter.bates is giving me Login failed. No profile has been set up for this user. Contact your administrator., even though it is showing up in the list of users.
So, is there a way to delete the ACME.xml from the portal. Thank you :)
