# ldaptool

CLI tool to query LDAP/AD servers

* Configuration file to configure "realms"
  * DNS domain (mapping to ldap search base as DC labels)
  * LDAP servers in that domain
  * Bind account
  * Integration with password managers
* Various output formats
  * Classic LDIF
  * JSON stream (with detailed or simplified attribute values)
  * CSV
  * Markdown table with stretched columns (for viewing in CLI/for monospaces fonts)
* Decodes certain well-known attributes (UUIDs, Timestamps, SID, userAccountControl)
* Requires server to support [RFC 2696: Simple Paged Results](https://www.rfc-editor.org/rfc/rfc2696) for proper pagination
  * By default the first 1000 entries are shown, and it errors if there are more results
  * Use `--all` to show all results

## Authentication, Protocol, Ports

`ldaptool` always uses TLS for password based authentication, and SASL GSS-API over non-TLS for Kerberos ones.

## Config file

Location: `~/.config/ldaptool.yaml`

### Realms

```yaml
realms:
  EXAMPLE:
    domain: "example.com"
    servers: server1 server2
    account: "bind@example.com"
    password_folder: mainaccounts
  EXAMPLE.admin:
    domain: "example.com"
    servers: server1 server2
    account: "CN=admin,OU=Admins,DC=example,DC=com"
    password_folder: adminaccounts
  EXAMPLE.admin2:
    domain: "example.com"
    servers: server1 server2
    account: "CN=admin,OU=Admins,DC=example,DC=com"
    password_file: localadmin2
    password_folder: adminaccounts
  SUB:
    domain: "sub.example.com"
    servers: subserver1 subserver2
    forest_root_domain: "example.com"
```

The `servers` field is a whitespace separates list of hostnames in the domain.

If a password manager is used, the `password_file` (defaults to names derived from `account`) and `password_folder` fields determine the name of the file ("secret") queried from the password manager.  Here the following file names would be used:
* `EXAMPLE`: `mainaccounts/bind`
* `EXAMPLE.admin`: `adminaccounts/example.com/Admins/admin`
* `EXAMPLE.admin2`: `adminaccounts/localadmin2`

If the `account` field isn't present `ldaptool` always uses kerberos; if `--krb` is used, `account` is ignored.

Windows AD has a concept of a "global catalog" across all domains in a AD Forest; it uses separate ports (3268 without TLS and 3269 with TLS).
The `forest_root_domain` field can be used to set a search base for global catalog (`--gc`) queries (usually the forest root should be parent domain).

Unless specified with `--base` the search base is derived from `domain` (or `forest_root_domain` with `--gc`) as `DC=...` for each DNS label.

#### Script as password manager

```yaml
password-script: keyring local decrypt
```

This configures a script as password manager.

Either takes a string (split by [`shlex.split`](https://docs.python.org/3/library/shlex.html#shlex.split)) or a list of strings.
The password name is appended as last argument.

#### keyringer

```yaml
keyringer:
  keyring: yourkeyringname
  folder: ldapquery
```

This configures [`keyringer`](https://0xacab.org/rhatto/keyringer) (based on GPG) as password manager.

`keyringer` need a "keyring" to search in, and you can (optionally) specify a folder to be
prefixed to the password names created from the realm.

#### keepass

```yaml
keepass: /home/me/mypasswords.kdbx
```

This configures KeePass as password manager; it will prompt for your master password every time.
