Hi, I'm new to Galaxy. It looks pretty impressive, but I'm having a hard time to understand the logic in how user accounts are managed. I created two accounts manually. They are identified using e-mail adresses, but lets refer to them as A and B to keep it short. Then I've setup my galaxy installation to use external authentication with the ldap server of our university. To test whether automatic creation of new accounts works I deleted account A. I also purged the deleted accounts. In the database both accounts are still present. Account A has a 1 in the columns for "deleted" and "purged". Now if I try to login with again the same e-mail address as for A, I would expect a new account will be created, but that is not the case. I can login with account A, but I do not see a new third account popup in the galaxy_user table. Using the admin page from the web interface I can see only one account: B. So somehow the old account is still used although it is no longer visible in the web interface. If I now list the details for account B, I can see that a role with the same name as account A still exists. I can assign this role to B. When I click save and go back to the list of users, the role column for account B is updated from 1 -> 2. I assume this is to indicate that user B now has two roles, although one of them belongs to an account that should not exist. When I go back to the details for account B and remove role A, click save and go back to the overview of users, the column "roles" lists "3" for account B. Going back to the details for B reveals role A was not removed. Trying again won't help to remove role A from user B, but each time I try the amount of roles for user B is incremented with 1 in the overview of users... Therefore I have two questions: Is this the way it is supposed to work? I noticed there are scripts to delete userless histories, purge histories and purge datasets, but how do I really really delete a user?
