Hi all,
first of all, thank you for the last release of GWM. it's becoming a
very useful tool in my daily tasks.
I'm having some issues with the configuration of ldap support in the
last 0.11 stable. I can see from the documentation that a fab ldap
command is required after creating the ldap_settings.py ; but the
command fails with:

[localhost] local: venv/bin/pip install -q -r requirements/ldap.txt
/bin/sh: 1: venv/bin/pip: not found

Fatal error: local() encountered an error (return code 127) while
executing 'venv/bin/pip install -q -r requirements/ldap.txt'

Aborting.

i have executed a source /opt/ganeti_webmgr/bin/activate before that.
Also, the requirements/ldap.txt file was missing - i recovered it from
an old GWM installation.

I'm a bit confused - the installation right now is not performed anymore
with "fab" (i executed it with the new installation script) but from the
documentation i see a reference to fab for ldap support.

Any hint?
thank you very much.

Hi Gianfilippo,

Thanks for the report. I took a look at how LDAP works, and it's
currently a little broken. The pieces are all there, but in redoing
the settings in 0.11 we broke the ldap settings import.

I've made a preliminary fix that works locally, and will hopefully
have a release candidate that fixes your issue out shortly. I'll also
be sure to update the docs on how to get it to work successfully.

Thanks!

Evan Tschuy

Hello Evan,
thanks for your support. I'm testing now RC2, but it seems i really
cannot get LDAP working.
I have performed the actions described in the updated config instructions:

- installed the described package dependencies for deb based systems
- executed pip install -r requirements/ldap.txt from install dir
- customized ldap_settings.py and put it in /opt/ganeti_webmgr and
/opt/ganeti_webmgr/config (to be sure)

Trying to login, i get an auth error and, checking with tcpdump, no
connection attempt is performed to my LDAP server.
I've also set logger.setLevel(logging.DEBUG) in my ldap_settings.py
file, but i don't get any message in my apache logs or syslog.

Anything else to check?
Sorry, i'm a bit of a novice on python. Cheers

Hello,
I managed to fix the issue. It seems that you need to edit
ganeti_webmgr-0.11.1-rc2/ganeti_webmgr/ganeti_web/settings/ldap_settings.py
*before* executing ./scripts/setup.sh -D mysql
(the documentation was not clear about this - it described the LDAP
operations only in the "configuration" section, that is after the
installation part).
Editing ldap_settings.py before executing the install fixed my issue.

Another thing, for all openldap users out there: if you're using
posixGroup type and not GroupOfNames for your LDAP groups, you need to
change the ldap_settings.py file as follows:

# LDAP Authentication via django-auth-ldap
# http://packages.python.org/django-auth-ldap/#reference
import ldap
from django_auth_ldap.config import LDAPSearch, PosixGroupType

and

AUTH_LDAP_GROUP_SEARCH = LDAPSearch("ou=group,dc=example,dc=net",
ldap.SCOPE_SUBTREE,
"(objectClass=posixGroup)")


and

AUTH_LDAP_GROUP_TYPE = PosixGroupType()

Cheers
