LDAP + User Groups authentication plugin not working after upgrade to 4.19.x
After upgrading our RhodeCode EE server to 4.19.3, the LDAP + User Groups authentication plugin no longer works for us. I get "invalid username/password" errors when trying to log in with an LDAP account. If I switch the server to the regular LDAP plugin, it works fine with the same settings.
The problem appears to have first occurred in 4.19.0. I tested this by updating a copy of our server from 4.18.3 (where the LDAP + Groups authentication plugin worked) to 4.19.0 (where it did not).
I see this error in the log file when the authentication failure occurs:

We'll take a look into this, as a workaround you can copy the old ldap_group.so plugin from the backup folder:
cp ~/.rccontrol/enterprise-1/backup/lib/python2.7/site-packages/rc_auth_plugins/auth_ldap_group.so ~/.rccontrol/enterprise-1/profile/lib/python2.7/site-packages/rc_auth_plugins/auth_ldap_group.so
