LDAP Sequence Diagram with Kerberos

This flow covers LDAP search with Kerberos authentication and the ciphered interactions that follow. To analyze an LDAP capture of your own, VisualEther renders the Wireshark PCAP as a sequence diagram and Claude Code can read the bind and search exchange.

This sequence diagram describes authenticated LDAP directory lookup. The steps covered are:

1. TCP connection establishment with the LDAP server
2. Initial interaction to list the available services.
3. Authenticate with the Kerberos server and obtain a ticket to proceed with the authentication with the LDAP server.
4. Armed with the Kerberos ticket, the LDAP client uses bind to authenticate and initiate a secure connection.
5. Encrypted LDAP communication follows after that.
