# Guichet
|
|
|
|
[](https://woodpecker.deuxfleurs.fr/repos/37)
|
|
|
|
Guichet is a simple LDAP web interface for the following tasks:
|
|
|
|
- self-service password change
|
|
- administration of the LDAP directory
|
|
- inviting new users to create accounts
|
|
|
|
Guichet works well with the [Bottin](https://bottin.eu) LDAP server.
|
|
Currently, Guichet's templates are only in French as it has been created for
|
|
the [Deuxfleurs](https://deuxfleurs.fr) collective.
|
|
We would gladly merge a pull request with an English transaltion !
|
|
|
|
A Docker image is provided on the [Docker hub](https://hub.docker.com/r/lxpz/guichet_amd64).
|
|
An example for running Guichet on a Nomad cluster can be found in `guichet.hcl.example`.
|
|
|
|
Guichet takes a single command line argument, `-config <filename>`, which is the
|
|
path to its config file (defaults to `./config.json`).
|
|
The configuration file is a JSON file whose contents is described in the following section.
|
|
|
|
Guichet is licensed under the terms of the GPLv3.
|
|
|
|
|
|
## Building Guichet
|
|
|
|
Guichet requires go 1.13 or later.
|
|
|
|
To build Guichet, clone this repository outside of your `$GOPATH`.
|
|
Then, run `make` in the root of the repo.
|
|
|
|
|
|
## Configuration of Guichet
|
|
|
|
Guichet is configured using a simple JSON config file which is a dictionnary whose keys
|
|
are described below. An example is provided in a further section.
|
|
|
|
### HTTP listen address
|
|
|
|
- `http_bind_addr`: which IP and port to bind on for the HTTP web interface. Guichet does not support HTTPS, use a reverse proxy for that.
|
|
|
|
### LDAP server configuration
|
|
|
|
- `ldap_server_addr`: the address of the LDAP server to use
|
|
- `ldap_tls` (boolean): whether to attempt STARTTLS on the LDAP connection
|
|
- `base_dn`: the base LDAP object under which we are allowed to view and modify objects
|
|
|
|
### User and group configuration
|
|
|
|
- `user_base_dn`: the base LDAP object that contains user accounts
|
|
- `user_name_attr`: the search attribute for user identifiers (usually `uid` or `cn`)
|
|
- `group_base_dn` and `group_name_attr`: same for groups
|
|
|
|
### Administration configuration
|
|
|
|
- `admin_account`: DN of an LDAP account that has administrative privilege. If such an account is set, the admin can log in by entering the full DN in the login form.
|
|
- `group_can_admin`: DN of a LDAP group whose members are given administrative privilege
|
|
|
|
### Invitation configuration
|
|
|
|
Guichet supports a mechanism where users can send invitations by email to other users.
|
|
The ability to send such invitations can be configured to be restricted to a certain group of users.
|
|
Invitation codes are created as temporary LDAP objects in a special folder.
|
|
|
|
- `group_can_invite`: the LDAP DN of a group whose members are allowed to send invitations to new users
|
|
- `invitation_base_dn`: the LDAP folder in which invitation codes are stored
|
|
- `invitation_name_attr`: just use `cn`
|
|
- `invited_mail_format`: automatically set the invited user's email to this string, where `{}` is replaced by the created username (ex: `{}@deuxfleurs.fr`)
|
|
- `invited_auto_groups` (list of strings): a list of DNs of LDAP groups
|
|
|
|
#### Email configuration
|
|
|
|
Guichet can send an invitation link by email. To do so, an SMTP server must be configured:
|
|
|
|
- `smtp_server`: the host and port of the mail server
|
|
- `smtp_username` and `smtp_password`: the username and password to log in with on the mail server
|
|
- `mail_from`: the sender email address for the invitation message
|
|
- `web_address`: the base web address of the Guichet service (used for building the invitation link)
|
|
|
|
## Example configuration
|
|
|
|
This is a subset of the configuration we use on Deuxfleurs:
|
|
|
|
```
|
|
{
|
|
"http_bind_addr": ":9991",
|
|
"ldap_server_addr": "ldap://bottin2.service.2.cluster.deuxfleurs.fr:389",
|
|
|
|
"base_dn": "dc=deuxfleurs,dc=fr",
|
|
"user_base_dn": "ou=users,dc=deuxfleurs,dc=fr",
|
|
"user_name_attr": "cn",
|
|
"group_base_dn": "ou=groups,dc=deuxfleurs,dc=fr",
|
|
"group_name_attr": "cn",
|
|
|
|
"admin_account": "cn=admin,dc=deuxfleurs,dc=fr",
|
|
"group_can_admin": "cn=admin,ou=groups,dc=deuxfleurs,dc=fr",
|
|
"group_can_invite": "cn=asso_deuxfleurs,ou=groups,dc=deuxfleurs,dc=fr"
|
|
}
|
|
```
|
|
|
|
Here is an example of Bottin ACLs that may be used to support Guichet invitations:
|
|
|
|
```
|
|
"acl": [
|
|
"*,dc=deuxfleurs,dc=fr::read:*:* !userpassword",
|
|
"*::read modify:SELF:*",
|
|
"ANONYMOUS::bind:*,ou=users,dc=deuxfleurs,dc=fr:",
|
|
"ANONYMOUS::bind:cn=admin,dc=deuxfleurs,dc=fr:",
|
|
"*,ou=services,ou=users,dc=deuxfleurs,dc=fr::bind:*,ou=users,dc=deuxfleurs,dc=fr:*",
|
|
"*,ou=services,ou=users,dc=deuxfleurs,dc=fr::read:*:*",
|
|
|
|
"*:cn=asso_deuxfleurs,ou=groups,dc=deuxfleurs,dc=fr:add:*,ou=invitations,dc=deuxfleurs,dc=fr:*",
|
|
"ANONYMOUS::bind:*,ou=invitations,dc=deuxfleurs,dc=fr:",
|
|
"*,ou=invitations,dc=deuxfleurs,dc=fr::delete:SELF:*",
|
|
|
|
"*:cn=asso_deuxfleurs,ou=groups,dc=deuxfleurs,dc=fr:add:*,ou=users,dc=deuxfleurs,dc=fr:*",
|
|
"*,ou=invitations,dc=deuxfleurs,dc=fr::add:*,ou=users,dc=deuxfleurs,dc=fr:*",
|
|
|
|
"*:cn=asso_deuxfleurs,ou=groups,dc=deuxfleurs,dc=fr:modifyAdd:cn=email,ou=groups,dc=deuxfleurs,dc=fr:*",
|
|
"*,ou=invitations,dc=deuxfleurs,dc=fr::modifyAdd:cn=email,ou=groups,dc=deuxfleurs,dc=fr:*",
|
|
"*:cn=asso_deuxfleurs,ou=groups,dc=deuxfleurs,dc=fr:modifyAdd:cn=seafile,ou=groups,dc=deuxfleurs,dc=fr:*",
|
|
"*,ou=invitations,dc=deuxfleurs,dc=fr::modifyAdd:cn=seafile,ou=groups,dc=deuxfleurs,dc=fr:*",
|
|
|
|
"cn=admin,dc=deuxfleurs,dc=fr::read add modify delete:*:*",
|
|
"*:cn=admin,ou=groups,dc=deuxfleurs,dc=fr:read add modify delete:*:*"
|
|
]
