`models` does far too much. In particular it handles all `UserSignin`. It shouldn't be responsible for calling LDAP, SMTP or PAM for signing in. Therefore we should move this code out of `models`. This code has to depend on `models` - therefore it belongs in `services`. There is a package in `services` called `auth` and clearly this functionality belongs in there. Plan: - [x] Change `auth.Auth` to `auth.Method` - as they represent methods of authentication. - [x] Move `models.UserSignIn` into `auth` - [x] Move `models.ExternalUserLogin` - [x] Move most of the `LoginVia*` methods to `auth` or subpackages - [x] Move Resynchronize functionality to `auth` - Involved some restructuring of `models/ssh_key.go` to reduce the size of this massive file and simplify its files. - [x] Move the rest of the LDAP functionality in to the ldap subpackage - [x] Re-factor the login sources to express an interfaces `auth.Source`? - I've done this through some smaller interfaces Authenticator and Synchronizable - which would allow us to extend things in future - [x] Now LDAP is out of models - need to think about modules/auth/ldap and I think all of that functionality might just be moveable - [x] Similarly a lot Oauth2 functionality need not be in models too and should be moved to services/auth/source/oauth2 - [x] modules/auth/oauth2/oauth2.go uses xorm... This is naughty - probably need to move this into models. - [x] models/oauth2.go - mostly should be in modules/auth/oauth2 or services/auth/source/oauth2 - [x] More simplifications of login_source.go may need to be done - Allow wiring in of notify registration - *this can now easily be done - but I think we should do it in another PR* - see #16178 - More refactors...? - OpenID should probably become an auth Method but I think that can be left for another PR - Methods should also probably be cleaned up - again another PR I think. - SSPI still needs more refactors.* Rename auth.Auth auth.Method * Restructure ssh_key.go - move functions from models/user.go that relate to ssh_key to ssh_key - split ssh_key.go to try create clearer function domains for allow for future refactors here.

# Gitea LDAP Authentication Module
|
|
|
|
## About
|
|
|
|
This authentication module attempts to authorize and authenticate a user
|
|
against an LDAP server. It provides two methods of authentication: LDAP via
|
|
BindDN, and LDAP simple authentication.
|
|
|
|
LDAP via BindDN functions like most LDAP authentication systems. First, it
|
|
queries the LDAP server using a Bind DN and searches for the user that is
|
|
attempting to sign in. If the user is found, the module attempts to bind to the
|
|
server using the user's supplied credentials. If this succeeds, the user has
|
|
been authenticated, and his account information is retrieved and passed to the
|
|
Gogs login infrastructure.
|
|
|
|
LDAP simple authentication does not utilize a Bind DN. Instead, it binds
|
|
directly with the LDAP server using the user's supplied credentials. If the bind
|
|
succeeds and no filter rules out the user, the user is authenticated.
|
|
|
|
LDAP via BindDN is recommended for most users. By using a Bind DN, the server
|
|
can perform authorization by restricting which entries the Bind DN account can
|
|
read. Further, using a Bind DN with reduced permissions can reduce security risk
|
|
in the face of application bugs.
|
|
|
|
## Usage
|
|
|
|
To use this module, add an LDAP authentication source via the Authentications
|
|
section in the admin panel. Both the LDAP via BindDN and the simple auth LDAP
|
|
share the following fields:
|
|
|
|
* Authorization Name **(required)**
|
|
* A name to assign to the new method of authorization.
|
|
|
|
* Host **(required)**
|
|
* The address where the LDAP server can be reached.
|
|
* Example: mydomain.com
|
|
|
|
* Port **(required)**
|
|
* The port to use when connecting to the server.
|
|
* Example: 636
|
|
|
|
* Enable TLS Encryption (optional)
|
|
* Whether to use TLS when connecting to the LDAP server.
|
|
|
|
* Admin Filter (optional)
|
|
* An LDAP filter specifying if a user should be given administrator
|
|
privileges. If a user accounts passes the filter, the user will be
|
|
privileged as an administrator.
|
|
* Example: (objectClass=adminAccount)
|
|
|
|
* First name attribute (optional)
|
|
* The attribute of the user's LDAP record containing the user's first name.
|
|
This will be used to populate their account information.
|
|
* Example: givenName
|
|
|
|
* Surname attribute (optional)
|
|
* The attribute of the user's LDAP record containing the user's surname This
|
|
will be used to populate their account information.
|
|
* Example: sn
|
|
|
|
* E-mail attribute **(required)**
|
|
* The attribute of the user's LDAP record containing the user's email
|
|
address. This will be used to populate their account information.
|
|
* Example: mail
|
|
|
|
**LDAP via BindDN** adds the following fields:
|
|
|
|
* Bind DN (optional)
|
|
* The DN to bind to the LDAP server with when searching for the user. This
|
|
may be left blank to perform an anonymous search.
|
|
* Example: cn=Search,dc=mydomain,dc=com
|
|
|
|
* Bind Password (optional)
|
|
* The password for the Bind DN specified above, if any. _Note: The password
|
|
is stored in plaintext at the server. As such, ensure that your Bind DN
|
|
has as few privileges as possible._
|
|
|
|
* User Search Base **(required)**
|
|
* The LDAP base at which user accounts will be searched for.
|
|
* Example: ou=Users,dc=mydomain,dc=com
|
|
|
|
* User Filter **(required)**
|
|
* An LDAP filter declaring how to find the user record that is attempting to
|
|
authenticate. The '%s' matching parameter will be substituted with the
|
|
user's username.
|
|
* Example: (&(objectClass=posixAccount)(uid=%s))
|
|
|
|
**LDAP using simple auth** adds the following fields:
|
|
|
|
* User DN **(required)**
|
|
* A template to use as the user's DN. The `%s` matching parameter will be
|
|
substituted with the user's username.
|
|
* Example: cn=%s,ou=Users,dc=mydomain,dc=com
|
|
* Example: uid=%s,ou=Users,dc=mydomain,dc=com
|
|
|
|
* User Search Base (optional)
|
|
* The LDAP base at which user accounts will be searched for.
|
|
* Example: ou=Users,dc=mydomain,dc=com
|
|
|
|
* User Filter **(required)**
|
|
* An LDAP filter declaring when a user should be allowed to log in. The `%s`
|
|
matching parameter will be substituted with the user's username.
|
|
* Example: (&(objectClass=posixAccount)(cn=%s))
|
|
* Example: (&(objectClass=posixAccount)(uid=%s))
|
|
|
|
**Verify group membership in LDAP** uses the following fields:
|
|
|
|
* Group Search Base (optional)
|
|
* The LDAP DN used for groups.
|
|
* Example: ou=group,dc=mydomain,dc=com
|
|
|
|
* Group Name Filter (optional)
|
|
* An LDAP filter declaring how to find valid groups in the above DN.
|
|
* Example: (|(cn=gitea_users)(cn=admins))
|
|
|
|
* User Attribute in Group (optional)
|
|
* Which user LDAP attribute is listed in the group.
|
|
* Example: uid
|
|
|
|
* Group Attribute for User (optional)
|
|
* Which group LDAP attribute contains an array above user attribute names.
|
|
* Example: memberUid
