hello folks, i had little difficulty setting up the balanced proxies and ldap auth, thanks to your wiki and mailing list. but now i'm running into an odd problem i'm hope you fellas can help shine some light on... i set up multiple galaxy sites running as different users (in the same group), with each site submitting to a different sge cluster (based on users sge env vars), but all use the same postgresql db and a common database/ folder. i get an error when i try to add a dataset in the library admin view. however i can add folders, no problem.
