Problem with sessions
Sometimes working with Lemonldap get error 500 with following message in /var/log/apache2/error.log:
[Fri Oct 09 10:11:55.154603 2015] [:error] [pid 18555:tid 140486618633984] Not a CODE reference at /usr/local/share/perl/5.20.1/Lemonldap/NG/Common/Session.pm line 152.\n
Not sure if it browser or lemonldap issue.
Sometimes problem dissapears without any actions besides refreshing the page, sometimes with restarting apache2
