Problem with trac and ldap

[stoychev@…]

Hello! I've done some settings with trac including LdapPlugin-0.5.1dev-py2.4.egg. I've read manual but still can't make it work.

Traceback (most recent call last):
  File "/var/lib/python-support/python2.4/trac/web/main.py", line 387, in dispatch_request
    dispatcher.dispatch(req)
  File "/var/lib/python-support/python2.4/trac/web/main.py", line 183, in dispatch

Please give any suggestions :(
