I'm having a problem logging into my mediawiki account on our local server. Other users are able to login normally. I didn't setup the mediawiki but have taken over administration of it as well as the local servers. It uses the LdapAuthenticationPlugin to authenticate with our LDAP user database. When i try to login using my LDAP user/pass, i just see a blank page with no errors (if i use an invalid password then i receive normal error about wrong password).

On the server the mediawiki is running on, this is what shows up in the httpd/access_log after i click the "Log in" button:

IP-addr - - [08/Nov/2016:14:40:30 -0700] "POST /index.php?title=Special:UserLogin&action=submitlogin&type=login HTTP/1.1" 500 - "https://host/index.php/Special:UserLogin" "Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0"

and this is what shows up in the httpd/error_log:
