(where an "other domain" is a domain that is not $env{'request.role.domain'}.

Bug 5595 and bug 5711.
Improvements to display of available actions for user lists.

- &show_user_lists() can take an extra argument - $formname (defaults to 'studentform').

- &course_sections() can take a third (optional argument) which is the single section currently stored.  The existing sections pulldown includes this section as the selected item.

Bug 5545. User can choose to display either "Modify user" or User's "About Me" page in a pop-up window.  Display of inline nav suppressed and "Close window" link provided at the end of the page in pop-up window.

Javascript error reported by IE when there are spaces in the title argument passed to open() function to open pop-up window used for date/section setting.

Bug 5545. User can choose to display a user's 'about me" page in a new window.

- &section_group_filter(): move initialization of @options inside loop, in case additional filters are added.
- call to lonnet::retrievestudentphoto() for full size image occurs immediately before call for thumbnail, during initial parse of %userlist.
- Add additional index to array, for each userlist item, (for thumbnail of student photo).

balance parentheses

In course context, only retrieve the classlist if rolefilter includes students.

bugs 5661, 5662.
- request for urls to access photos (both thumbnails and full size images) served from library server (via token mechanism), moved to occur during first pass of %userlist.
- eliminates timing problems caused when tokens were being requested as table display was being generated.

- Check supplied role for each user against @permitted_roles (not @courseroles) so custom roles can be assigned.

- Move "Proceed" button which executes the bulk action
- Add a "go" button to the right of the select action pulldown menu to open the date/section pop-up window, or display an alert dialog if no date/section window needed for the currently selected action.

- Confirmation dialog for bulk actions including warnings if no start or end date have been selected, or no section has been selected.
- Correct javascript to pass value of checked retainsec radio button in pop-up window to opener.
- Expire sectionless role if retainsec set to off, and section is being switched.

- Exclude privileged users from user list display of course users, (non-student roles) unless course environment settings require inclusion of the user
- Some @ -> : replacements for username, domain separator
- Change so checking of 'nothideprivileged' setting for course can accommodate usernames containing '@'

- switch on value of currently checked login radio button.

- aggregate setting of $authform_* variables in loncreateuser with &initialize_authen_form()

- Added &domain_roles_select() - used for linked role type and role selection boxes for DC, when displaying user roles.
- Display of active advanced roles when viewing course classlist eliminated
  - replaced with selectable advanced roles in role filter for user lists.

loncoursedata.pm
- Three subroutines added to return indices for permanentemail, role and extent, so user listings in lonuserutils:;show_user_lists() can sort by these using the existing sorting code.

loncreateuser.pm
- display of user lists included in menu on first page.
- some wording changes (as per bug 5506)
- switches on $env{'form.state'} for call to &print_userlist() eliminated (not needed).
- course selector included when in DC context

lonpickcourse.pm

Work in progress - role expiration and section switching still to be added to interface.
