Installation

$ git clone https://github.com/Macmod/godap
$ cd godap
$ go install .

Usage

Bind with username and password

$ godap <hostname or IP> -u <username> -p <password> -d <domain>

or

$ godap <hostname or IP> -u <username>@<domain> -p <password>

Bind with an NTLM hash

$ godap <hostname or IP> -u <username> -H <hash> [-d <domain>]

Bind with a Kerberos ticket

$ KRB5CCNAME=ticket.ccache godap <hostname or IP> -k -d <domain> -t ldap/<DC hostname>

Anonymous Bind

$ godap <hostname or IP>

LDAPS/StartTLS

To use LDAPS for the initial connection (ignoring certificate validation) run:

$ godap <hostname or IP> [bind flags] -S -I

To use StartTLS to upgrade an existing connection to use TLS, use the Ctrl + u keybinding inside godap.

Notice that, if the server certificate is not trusted by your client, you must either have started godap with -I to use the upgrade command properly or toggle the IgnoreCert checkbox using the l keybinding before upgrading.

If LDAPS is available, you can also change the port using l, toggle the LDAPS checkbox, set the desired value for IgnoreCert, and reconnect with Ctrl + r.

SOCKS

To connect to LDAP through a SOCKS proxy include the flag -x schema://ip:port, where schema is one of socks4, socks4a or socks5.

You can also change the address of your proxy using the l keybinding.

Flags

• -u,--username - Username for bind
• -p,--password - Password for bind
• --passfile - Path to a file containing the password for bind
• -P,--port - Custom port for the connection (default: 389 or 636 when -S is provided)
• -r,--rootDN <distinguishedName> - Initial root DN (default: automatic)
• -f,--filter <search filter> - Initial LDAP search filter (default: (objectClass=*))
• -E,--emojis - Prefix objects with emojis (default: true, to change use -emojis=false)
• -C,--colors - Colorize objects (default: true, to change use -colors=false)
• -A,--expand - Expand multi-value attributes (default: true, to change use -expand=false)
• -L,--limit - Number of attribute values to render for multi-value attributes when -expand is true (default: 20)
• -F,--format - Format attributes into human-readable values (default: true, to change use -format=false)
• -M,--cache - Keep loaded entries in memory while the program is open and don't query them again (default: true)
• -D,--deleted - Include deleted objects in all queries performed (default: false)
• -T,--timeout - Timeout for LDAP connections in seconds (default: 10)
• -I,--insecure - Skip TLS verification for LDAPS/StartTLS (default: false)
• -S,--ldaps - Use LDAPS for initial connection (default: false)
• -G,--paging - Paging size for regular queries (default: 800)
• -d,--domain - Domain name for NTLM / Kerberos authentication
• -H,--hashes - Hashes for NTLM bind
• -k,--kerberos - Use Kerberos ticket for authentication (CCACHE specified via KRB5CCNAME environment variable)
• -t,--spn - Target SPN to use for Kerberos bind (usually ldap/dchostname)
• --hashfile - Path to a file containing the hashes for NTLM bind
• -x,--socks - URI of SOCKS proxy to use for connection (supports socks4://, socks4a:// or socks5:// schemas)
• -s,--schema - Load GUIDs from schema on initialization (default: false)
• --kdc - Address of the KDC to use with Kerberos authentication (optional: only if the KDC differs from the specified LDAP server)
• --timefmt - Time format for LDAP timestamps. Options: eu, us, iso8601, or define your own using go time format (default: eu)

Keybindings

Tree Colors

The nodes in the explorer tree are colored as follows:

* Before v2.2.0, disabled nodes were colored red. This was the only custom color in the tree panel; other nodes were colored with default colors (the "include deleted objects" flag had not been implemented yet).

Contributing

Godap started as a fun side project, but has become a really useful tool since then. Unfortunately these days I only have limited time and there's much to be done, so if you like the tool and believe you can help please reach out to me directly at @marzanol :-)

Contributions are also welcome by opening an issue or by submitting a pull request.

Acknowledgements

• DACL parsing code and SOCKS code were adapted from the tools below:

  • ldapper
  • Darksteel

• BadBlood was also very useful for testing during the development of the tool.

Disclaimers

• Although some features might work with OpenLDAP (mainly in the explorer/search pages), the main focus of this tool is Active Directory.
• All features were tested and seem to be working properly on a Windows Server 2019, but this tool is highly experimental and I cannot test it extensively - I don't take responsibility for modifications that you execute and end up impacting your environment. If you observe any unexpected behaviors please let me know so I can try to fix it.
