LDAP "valid_users" groups with spaces not properly handled

Trac - 1.0.9

Using a LDAP group with spaces in it for group_validusers field.

Expected behavior

Properly authenticates users in the "Example Employees" group.

Actual behavoir

Server throws error 500.


See line 58 of log file where auth module tries to search LDAP for normalized (lowercase/underscored) version of the group (example_employees).

Expected behavior is achieved when group_validusers is set to a group without spaces. (tracusers)

I also had this problem... see attached

I made a simple change on line 357 that replaces _ back into a space. That resolves your problem.

I also had to disable LDAP referrals for it to work on my AD, that was on line 306.

Lastly, my corporation lists folks on AD CN with Lastname, Firstname and that , separating the Last and First needs escaping on the plugin, that change is on line 353.

In 16070:

refs #12680

  • added new config property group_spaces2underscore which defaults to true.

Set this property to false to retain the spaces.
