Setting up SSSD and vsFTPd

I'm currently trying to setup vsFTPd with Active Directory authentication through SSSD. My SSSD config seems to be working as 'id <username>' and 'getent passwd <username> works. However vsFTP seems to not be using SSSD correctly:

[root@StudentOrgFTP log]# ftp localhost Trying ::1... ftp: connect to address ::1Connection refused Trying 127.0.0.1... Connected to localhost (127.0.0.1). 220 (vsFTPd 3.0.2) Name (localhost:root): <username> 331 Please specify the password. Password: 530 Login incorrect. Login failed. ftp> 221 Goodbye. [root@StudentOrgFTP log]# cat secure 

/var/log/secure

I would really appreciate any input on what could be wrong.
