we are connecting to Active Directory using PrincipalContext (C# .Net)
System.DirectoryServices.AccountManagement.PrincipalContext class.
As per microsoft update:
Microsoft to disable use of unsigned LDAP port 389
https://msandbu.org/upcoming-change-microsoft-to-disable-use-of-unsigned-ldap-port-389/
Is there any impact on this as well. I don't find any docs regarding the same.
