Hi ahmedwerdany , 
Do you configure The DNS servers for F5 system ? you need to make sure that your F5 perform DNS resolution successfully. 
Are There any firewalls between F5 and AD servers ? 
if yes " you need to open (LDAP ports 389 udp and LDAPS port 636 TCP & udp)

> Also , I think you need authentication profile on your AD to identify F5.  

Follow this KB to review your Configuration :
