# SAML Auth \[Deprecated]

⚠️ **Microsoft retired this authentication mechanism**

This authentication option uses Microsoft Online Security Token Service `https://login.microsoftonline.com/extSTS.srf` and SAML tokens in order to obtain authentication cookie.

### Struct

```go
type AuthCnfg struct {
  // SPSite or SPWeb URL, which is the context target for the API calls
  SiteURL string `json:"siteUrl"`
  // Username for SharePoint Online, e.g. `[user]@[company].onmicrosoft.com`
  Username string `json:"username"`
  // User or App password
  Password string `json:"password"`
}
```

### JSON

`private.json` sample:

```javascript
{
  "siteUrl": "https://contoso.sharepoint.com/sites/test",
  "username": "john.doe@contoso.onmicrosoft.com",
  "password": "this-is-not-a-real-password"
}
```

### Code sample

```go
package main

import (
	"log"
	// "os"

	"github.com/koltyakov/gosip"
	strategy "github.com/koltyakov/gosip/auth/saml"
)

func main() {
	// authCnfg := &strategy.AuthCnfg{
	// 	SiteURL:  os.Getenv("SPAUTH_SITEURL"),
	// 	Username: os.Getenv("SPAUTH_USERNAME"),
	// 	Password: os.Getenv("SPAUTH_PASSWORD"),
	// }
	// or using `private.json` creds source

	authCnfg := &strategy.AuthCnfg{}
	configPath := "./config/private.json"
	if err := authCnfg.ReadConfig(configPath); err != nil {
		log.Fatalf("unable to get config: %v", err)
	}

	client := &gosip.SPClient{AuthCnfg: authCnfg}
	// use client in raw requests or bind it with Fluent API ...
}
```
