CIT Scenario not running via scheduler if LDAP port used is 636

Hi All,

CIT Scenario not running via scheduler if LDAP port used is 636 and ssl connection enabled, it works if i use port 389. 

If i run scenario manually via 636 port then it works but gets stopped if i try to run via scheduler, scheduler gets stopped with error "Unable to connect to Server on port 636. unable to open connector". when i check this connection test in scenario, its success. why its getting failed if scheduler starts it..

Thanks..
