CE: LDAPS authentication fails

Hi all,
dunno if this is the right place to report bugs… I’ll try.

Just installed Community Edition 4.0.1
Configured LDAP authentication.

I get the following traceback after an auth try:

2016-06-08 13:40:51.752 INFO  [rhodecode.authentication.base] Authenticating user `my.username` using egg:rhodecode-enterprise-ce#ldap plugin

any hint?


Hi Alessandro,

Thanks for reporting this. We’re working on a fix it will be available in next 1-2 days.

I had the same problem. I did a temporary workaround:

In “/opt/rhodecode/store/7xack0znza8fdx0wvdsz3sn9pwh9sz7p-python2.7-rhodecode-enterprise-ce-4.0.1/lib/python2.7/site-packages/rhodecode/authentication/plugins/auth_ldap.py”, comment out line 174 and 175
#if isinstance(ldap, Missing): # raise LdapImportError("Missing or incompatible ldap library")

After restarting my instance (rccontrol restart community-1), LDAP was working.

Looking forward to a more permanent fix.

Also hitting the same issue. For some reason, the workaround suggested above does not seem to do the trick.

Glad to hear you guys are already working on the fix!


actually release 4.1 is out already, feel free to update the issue should be fixed ! Sorry for the troubles guys.


Works like a charm… thank you for the amazingly fast response!!
