Ldaps not working with seafile 7.0.5 64-bit, on centos 8.2

Although seafile works with ldap://host, but it doesn’t work with ldaps
HOST = ldap://ad.hostname.ca
BASE=DC=ad,DC=hostname,DC=ca
USER_DN=OHDP_seafile_svc@ad.hostname.ca
PASSWORD=
LOGIN_ATTR=userPrincipalName
FILTER = objectClass=User
USE_PAGED_RESULT = true
FOLLOW_REFERRALS = false

Would need some clarity as the logs ccnet.log say ldap_bind failed with wrong username and password, but clearly the credential are fine.
I have also moved the libnssutil3.so file as mentioned in the documentation.
with ldaps search ldaps works, but for somereason i think seafile isn’t able to use ldapsearch or local libs. I am confused.

Any help will be deeply appreciated
