Small question on Authentication

Hi i have a very basic question. we are using APM for authenticating one of our application and we have integrated apm with active directory. I can see that APM is talking with AD on kerberos and LDAP. We have been given a task to make sure that F5 is not talking with AD on NTLM.

 

1. In the F5 APM flow, i can see that SSO is using NTLM
2. F5 is talking to AD on kerbaros & LDAP

i am unsure whether NTLM with AD would be used with AD. what ports ntlm uses? how can i make sure if F5 APM is not talking to AD on NTLMv1?
