Hi Oren,

I am posting the answer given to the galaxy-dev mailing list below for 
other users, even thought this is a development topic. Next time, please 
only post to a single mailing list.

Hi Oren,

Hrm, it looks like the option to delete users was removed from the 
interface since it couldn't be made conditional on a configuration 
setting (due to a limitation in Galaxy's "Grids" feature, which is used 
to display the table of users in the UI).  They can be added by 
uncommented lines 98-100 in lib/galaxy/web/controllers/admin.py:

     #operations.append( grids.GridOperation( "Delete", condition=( 
lambda item: not item.deleted ), allow_multiple=True ) )
     #operations.append( grids.GridOperation( "Undelete", condition=( 
lambda item: item.deleted and not item.purged ), allow_multiple=True ) )
     #operations.append( grids.GridOperation( "Purge", condition=( 
lambda item: item.deleted and not item.purged ), allow_multiple=True ) )

 > 2. Which call in the code deletes a user? I can then write my own API 
mark_user_deleted() in lib/galaxy/web/base/controller.py.  The preferred 
method for implementing API methods is by moving the code in the web UI 
controller which performs the actual action to lib/galaxy/actions/ and 
then changing the API and UI methods to call that method.  See the 
implementation of the Quota API for a reference.

Thanks for reporting these, we'll fix them as soon as possible.  I've 
created a bitbucket here to track them:
