FMC AD LDAPS failing

[Amen]

FMC Version 7.2.5.1
AD Integration failing when switched from LDAP to LDAPS with general error - check user/password/connectivity. AD Server is in the same network, accepting LDAPS from any source, user/password was double-checked, AD Root-CA certificate as well

i’ve added it to trusted Cas on FMC, is that what you ment?

“LDAPS” is Server with Cert Chain, and “LDAPS_Server_Only” is only the Server part
