Dear all, I am using LDAP authentication and auto registration options. LDAP authentication passed successfully, but I got error message during auto-registration process: File "/home/galaxy/galaxy/.venv/local/lib/python2.7/site-packages/sqlalchemy/engine/default.py", line 450, in do_execute cursor.execute(statement, parameters) sqlalchemy.exc.IntegrityError: (psycopg2.IntegrityError) duplicate key value violates unique constraint "ix_role_name" DETAIL: Key (name)=(marija.durdevic@medunigraz.at) already exists.

Anyhow, I would like to solve this issue and to register without errors. I tried to debug Galaxy code... It looks like that problem is somewhere with sessions... Script: Lib/galaxy/security/__init__.py Function: create_private_user_role( self, user ) In this line: self.sa_session.flush() Anny suggestion what can be wrong? Thanks in advance, Marija Mag.
