Authentication over ldap needs some logging

[yennor]

Is your feature request related to a problem? Please describe.
I'm using the docker image of weblate and just lost about 45 minutes trying to setup the ldap authentication. In the ip address of the ldap server I've had a mistake. But since there wasn't a single error message in the log file (i've activated debug), I was playing around forever with the dn_templte, dn_search etc. settings (which by the way are pretty bad documented). I've needed to read through settings_docker.py to be sure how they work.
Now everything is working. But still there is not a single mentioning of ldap or authentication in the logs.

Describe the solution you'd like
Give some log output, especially when something isn't working.

In shipped example configuration verbose LDAP logging is enabled when DEBUG mode is set:

weblate/weblate/settings_example.py

Lines 484 to 485 in 53c42ab

	# Django Authentication Using LDAP
	"django_auth_ldap": {"handlers": [DEFAULT_LOG], "level": DEFAULT_LOGLEVEL},

Even without that, it should log errors. What is your logging configuration?

This issue looks like a support question. We try to answer these reasonably fast, but in case you are looking for faster resolution, please consider purchasing support subscription and make Weblate stronger.

Nah, no support question. I've got everything working and am not planing to change the configuration again ;-).
My logging configuration is:
services:
weblate:
environment:
WEBLATE_DEBUG: 1

I can send you the whole log produced by docker if you want to. But I can guarantee you, there's no mention of ldap, dn, cn inside (that were the words I was grepping for).

On the other side, I've seen such logs in several cases :-). What version do you use? WEBLATE_LOGLEVEL not set?

[yennor]

I've just tried out:
WEBLATE_DEBUG: 1
WEBLATE_LOGLEVEL: DEBUG

and setting an invalid ldap server. => I can't log in ;-).
But not a single error message in the log file or any mentioning of ldap.
I'm using Weblate 4.2.1 with the current weblate docker-compose project. According to git pull it is uptodate.

Okay, just tried it, the log contains:

weblate_1   | uwsgi stderr | WARNING Caught LDAPError while authenticating fads: SERVER_DOWN({'result': -1, 'desc': "Can't contact LDAP server", 'errno': 22, 'ctrls': [], 'info': 'Invalid argument'})

My docker-compose.override.yml:

version: '3'
services:
  weblate:
    ports:
      - 80:8080
    environment:
      WEBLATE_SITE_DOMAIN: 127.0.0.1
      WEBLATE_AUTH_LDAP_SERVER_URI: ldap://ldap.example.org
      WEBLATE_AUTH_LDAP_USER_DN_TEMPLATE: uid=%(user)s,ou=People,dc=example,dc=net
      WEBLATE_AUTH_LDAP_USER_ATTR_MAP: first_name:name,email:mail
