OpenLDAP is quite picky about correct certificate chains.
No, the software will accept whatever you tell it to use, if you configure it appropriately. 


You really should create a full certificate chain, that is, a ca, a server certificate and a server key.


But yes, the Project always recommends that you do the right thing.
