Fixes#19555
Test-Instructions:
https://github.com/go-gitea/gitea/pull/21441#issuecomment-1419438000
This PR implements the mapping of user groups provided by OIDC providers
to orgs teams in Gitea. The main part is a refactoring of the existing
LDAP code to make it usable from different providers.
Refactorings:
- Moved the router auth code from module to service because of import
cycles
- Changed some model methods to take a `Context` parameter
- Moved the mapping code from LDAP to a common location
I've tested it with Keycloak but other providers should work too. The
JSON mapping format is the same as for LDAP.

There are 2 separate flows of creating a user: authentication and source
sync.
When a group filter is defined, source sync ignores group filter, while
authentication respects it.
With this PR I've fixed this behavior, so both flows now apply this
filter when searching users in LDAP in a unified way.
- Unified LDAP group membership lookup for authentication and source
sync flows
- Replaced custom group membership lookup (used for authentication flow)
with an existing listLdapGroupMemberships method (used for source sync
flow)
- Modified listLdapGroupMemberships and getUserAttributeListedInGroup in
a way group lookup could be called separately
- Added user filtering based on a group membership for a source sync
- Added tests to cover this logic

- Move the file `compare.go` and `slice.go` to `slice.go`.
- Fix `ExistsInSlice`, it's buggy
- It uses `sort.Search`, so it assumes that the input slice is sorted.
- It passes `func(i int) bool { return slice[i] == target })` to
`sort.Search`, that's incorrect, check the doc of `sort.Search`.
- Conbine `IsInt64InSlice(int64, []int64)` and `ExistsInSlice(string,
[]string)` to `SliceContains[T]([]T, T)`.
- Conbine `IsSliceInt64Eq([]int64, []int64)` and `IsEqualSlice([]string,
[]string)` to `SliceSortedEqual[T]([]T, T)`.
- Add `SliceEqual[T]([]T, T)` as a distinction from
`SliceSortedEqual[T]([]T, T)`.
- Redesign `RemoveIDFromList([]int64, int64) ([]int64, bool)` to
`SliceRemoveAll[T]([]T, T) []T`.
- Add `SliceContainsFunc[T]([]T, func(T) bool)` and
`SliceRemoveAllFunc[T]([]T, func(T) bool)` for general use.
- Add comments to explain why not `golang.org/x/exp/slices`.
- Add unit tests.

* Always use STARTTLS if available
* Provide CRAM-MD5 mechanism
* Add options for HELO hostname disabling
* Add options for providing certificates and keys
* Handle application specific password response as a failed user login
instead of as a 500.

Fix creation of new users:

prevents the creation of external users.
* The LoginSource refactor also broke this page.

`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.

* Only update keys if needed
* Add function to only list pubkey synchronized from ldap

* Some minor cleanup. Add integration tests (updete dep testify)
* Correction LDAP username validation
As https://msdn.microsoft.com/en-us/library/aa366101(v=vs.85).aspx describe spaces should not be in start or at the end of username but they can be inside the username. So please check my solution for it.
* Check for zero length passwords in LDAP module.
According to https://tools.ietf.org/search/rfc4513#section-5.1.2 LDAP client should always check before bind whether a password is an empty value. There are at least one LDAP implementation which does not return error if you try to bind with DN set and empty password - AD.

* Uppercase JSON suffix in constant names
* Proper case LoginNoType
* Prefix unexported template path constants with "tpl"
From https://godoc.org/crypto/tls#Config
ServerName is used to verify the hostname on the returned
certificates unless InsecureSkipVerify is given. It is also included
in the client's handshake to support virtual hosting unless it is
an IP address.
This is needed for certificate validation without InsecureSkipVerify.
This is feature is workaround for #2628 (JumpCloud) and some other services
that allow LDAP search only under BindDN user account, but not allow any LDAP
search query in logged user DN context.
Such approach is an alternative to minimal permissions security pattern for
BindDN user.
According to RFC 4511 4.2.1. Processing of the Bind Request "Clients may send
multiple Bind requests to change the authentication and/or security
associations or to complete a multi-stage Bind process. Authentication from
earlier binds is subsequently ignored."
Therefore we should not use 2 connections, but single one just sending two bind
requests.
Consider following LDAP search query example:
(&(objectClass=Person)(|(uid=%s)(mail=%s)))
Right now on first login attempt Gogs will use the text supplied on login form
as the newly created user name. In example query above the text matches against
both e-mail or user name. So if user puts the e-mail then the new Gogs user
name will be e-mail which may be undesired.
Using optional user name attribute setting we can explicitly say we want Gogs
user name to be certain LDAP attribute eg. `uid`, so even user will use e-mail
to login 1st time, the new account will receive correct user name.
