​http://barn.kerosenecow.net/ -- Registration disabled. This is mainly a showcase for development of the MG-GIMP project (a Mediagoblin plug-in that permits hosting of GIMP images and resources).

• Create... Server Error!

Links to page and page /register/ should not be available.

We are using the LDAP plugin for authentication. However, when we enable LDAP, after entering username and password, the site returns with

== Unhandled Exception ==
 

An unhandled exception was thrown by the application.

Pretty ugly...Proper error management and a nice error message at least would help because now we are stuck because we don't know if the config is wrong or there is a problem with mediagoblin.

Here's the config:

[plugins]
[[mediagoblin.plugins.geolocation]]
#[[mediagoblin.plugins.basic_auth]]
[[mediagoblin.media_types.image]]
[[mediagoblin.plugins.ldap]]
[[[server1]]]
LDAP_SERVER_URI = 'ldap://10.10.10.7:389'
LDAP_BIND_DN = 'cn=admin,dc=<HIDDEN>,dc=cc'
LDAP_BIND_PW = '<HIDDEN>'
LDAP_USER_DN_TEMPLATE = 'cn={username},ou=Users,dc=<HIDDEN>,dc=cc'
EMAIL_SEARCH_FIELD = 'mail'

The log file only prints:

2014-09-28 19:37:01,106 INFO    [mediagoblin.plugins.ldap.tools] Connecting to ldap://10.10.10.7:389.
2014-09-28 19:37:01,106 INFO    [mediagoblin.plugins.ldap.tools] Unbinding ldap://10.10.10.7:389.

So it seems it DOES connect to LDAP but for some reason it fails.

Using mediagoblin 0.7.1

Since the python 3 merge, database migrations no longer work. To produce the error you should run ./devtools/make_example_database.sh on the latest master (as of writing this it's ​1a2982d) to produce a un-migrated database. Then do ./bin/gmg dbupdate you will find an error will occur:
