Open Microscopy Environment

I got it! Ldap authentication works!
Thanks for your support. My base dn seemed to be wrong and i blanked out the field for the ldap groups.
But thanks again for support.

unfortunately during the testing phase another error occured.
at first we used django but now we want to switch to apache. i used the documentation but i'm getting an MOD_PYTHON ERROR at the end.

system:
opensuse 11.1 (64Bit)
apache 2.2.10-2.8.1
mod_python 3.3.1-147.35
python 2.6

the edited entries in the settings.py look like this:
DATABASE_NAME = '/srv/omero/webdb/db.sqlite3'
LOGDIR = '/srv/omero/weblog/'

those two directories (/srv/omero/webdb & /srv/omero/weblog) and subdirectories have the following permissions: -rw-rw-rw-
user: wwwrun
group: www
(the omero directory (/srv/omero/omero_dist/ has user:omero group:users)

the mod_python configuration is located in /etc/apache2/conf.d/ and looks like this:
<Location "/">
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE omeroweb.settings
PythonDebug On
PythonPath "['/srv/omero/omero_dist/lib/python', '/srv/omero/omero_dist/lib/python/omeroweb'] + sys.path"
</Location>


when configurating the web settings my console says:
omero@sandstorm:/srv/omero/omero_dist> bin/omero web settings
/srv/omero/omero_dist/lib/python/omeroweb/custom_settings.py already exist. Do you want to ovewrite it? (yes/no)no

/srv/omero/omero_dist/lib/python/omeroweb/initial_data.json already exist. Do you want to ovewrite it? (yes/no)no

You probably have an old OMEROweb.log in the /srv/omero/weblog directory with the wrong permissions. It should be safe to delete it.

Okay i've deleted all logfiles. Restarted Apache. Configured the websettings again (same results as posted above) and restarted omero.
But the error is still the same.

When you configure the web settings it writes to the log file as whatever user executes the command. Just delete the log file and hit a WebAdmin or WebClient page in your browser. If that doesn't work, try an Apache restart. If you're still in trouble, I'll need the output of ls -al /srv/omero/weblog.

Okay I've done what you said and the old error is gone BUT unfortunately a new one occurs:
When hitting webadmin or webclient I get an 404 Error from omero
I've attached the logfiles from /srv/weblog/

I'll need the output of the following:

Code: Select all

ls -al '/srv/omero/webdb/'
ls -al '/srv/omero/weblog/'

Okay, cool. What error are you getting then? The logs have no information I'm afraid.

I get an 404 Error from omero.

Can you be more specific? Just a 404? A screenshot perhaps?
