2.1.0 ldap authentication issue

Description

Since 2.1.0, ldap authentication no more works on YunoHost

Steps to Reproduce

1. Install mobilizon_ynh 2.1.0~ynh1 from YunoHost
2. Try to login with an yunohost ldap account: email and password
3. Receiving an error saying Unable to authenticate, your e-mail address or your password are invalid.

Expected behaviour:

Able to login

Actual behaviour:

We upgrade the mobilizon_ynh package from 2.0.2 to 2.1.0 in https://github.com/YunoHost-Apps/mobilizon_ynh/pull/134

Reproduces how often:

• Tested on a fresh 2.1.0~ynh1 install, with two differents ldap accounts, ldap authentication no more works
• Tested from a 2.0.2~ynh1 and 2.0.2~ynh2 with ldap authentication working, upgrading to 2.1.0~ynh1, and ldap authentication no more works

/etc/mobilizon/config.exs containing ldap configuration is the same in each version, so it don't seems to come from le mobilizon configuration Tests have been made on the exact same YunoHost version

Reported at: https://github.com/YunoHost-Apps/mobilizon_ynh/issues/135

Versions

mobilizon_ynh package is based on mobilizon release

Additional Information

Wasn't able to increase log to have more details of what happens during ldap authentication

Seems there is no difference on the ldaps and authentication files between 2.0.2 and 2.1.0

In the release files, the only thing I can notice, it's the upgrade of eldap from 1.2.9 to 1.2.10
