This may not be caused by your module, but I can only recreate the error on nginx servers running nginx-auth-ldap.
LDAP Server is Active Directory on Server 2012R2
ssl_check_cert is not specified in the config so I assume it is off, and authentication actually works as expected. However, the LDAP server keeps getting a fatal Schannel error (48). I tried importing the CA into the system-wide truststore of the nginx server, but the error still get's thrown in the Windows Server Event Logs.
