# Azure Active Directory authentication for Go
This is a standalone package for authenticating with Azure Active
Directory from other Go libraries and applications, in particular the [Azure SDK
for Go](https://github.com/Azure/azure-sdk-for-go).
Note: Despite the package's name it is not related to other "ADAL" libraries
maintained in the [github.com/AzureAD](https://github.com/AzureAD) org. Issues
should be opened in [this repo's](https://github.com/Azure/go-autorest/issues)
or [the SDK's](https://github.com/Azure/azure-sdk-for-go/issues) issue
trackers.
## Install
```bash
go get -u github.com/Azure/go-autorest/autorest/adal
```
## Usage
An Active Directory application is required in order to use this library. An application can be registered in the [Azure Portal](https://portal.azure.com/) by following these [guidelines](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-integrating-applications) or using the [Azure CLI](https://github.com/Azure/azure-cli).
### Register an Azure AD Application with secret
1. Register a new application with a `secret` credential
```
az ad app create \
--display-name example-app \
--homepage https://example-app/home \
--identifier-uris https://example-app/app \
--password secret
```
2. Create a service principal using the `Application ID` from previous step
```
az ad sp create --id "Application ID"
```
* Replace `Application ID` with `appId` from step 1.
### Register an Azure AD Application with certificate
1. Create a private key
```
openssl genrsa -out "example-app.key" 2048
```
2. Create the certificate
```
openssl req -new -key "example-app.key" -subj "/CN=example-app" -out "example-app.csr"
openssl x509 -req -in "example-app.csr" -signkey "example-app.key" -out "example-app.crt" -days 10000
```
3. Create the PKCS12 version of the certificate containing also the private key
```
openssl pkcs12 -export -out "example-app.pfx" -inkey "example-app.key" -in "example-app.crt" -passout pass:
```
4. Register a new application with the certificate content form `example-app.crt`
```
certificateContents="$(tail -n+2 "example-app.crt" | head -n-1)"
az ad app create \
--display-name example-app \
--homepage https://example-app/home \
--identifier-uris https://example-app/app \
--key-usage Verify --end-date 2018-01-01 \
--key-value "${certificateContents}"
```
5. Create a service principal using the `Application ID` from previous step
```
az ad sp create --id "APPLICATION_ID"
```
* Replace `APPLICATION_ID` with `appId` from step 4.
### Grant the necessary permissions
Azure relies on a Role-Based Access Control (RBAC) model to manage the access to resources at a fine-grained
level. There is a set of [pre-defined roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-built-in-roles)
which can be assigned to a service principal of an Azure AD application depending of your needs.
```
az role assignment create --assigner "SERVICE_PRINCIPAL_ID" --role "ROLE_NAME"
```
* Replace the `SERVICE_PRINCIPAL_ID` with the `appId` from previous step.
* Replace the `ROLE_NAME` with a role name of your choice.
It is also possible to define custom role definitions.
```
az role definition create --role-definition role-definition.json
```
* Check [custom roles](https://docs.microsoft.com/en-us/azure/active-directory/role-based-access-control-custom-roles) for more details regarding the content of `role-definition.json` file.
### Acquire Access Token
The common configuration used by all flows:
```Go
const activeDirectoryEndpoint = "https://login.microsoftonline.com/"
tenantID := "TENANT_ID"
oauthConfig, err := adal.NewOAuthConfig(activeDirectoryEndpoint, tenantID)
applicationID := "APPLICATION_ID"
callback := func(token adal.Token) error {
// This is called after the token is acquired
}
// The resource for which the token is acquired
resource := "https://management.core.windows.net/"
```
* Replace the `TENANT_ID` with your tenant ID.
* Replace the `APPLICATION_ID` with the value from previous section.
#### Client Credentials
```Go
applicationSecret := "APPLICATION_SECRET"
spt, err := adal.NewServicePrincipalToken(
*oauthConfig,
appliationID,
applicationSecret,
resource,
callbacks...)
if err != nil {
return nil, err
}
// Acquire a new access token
err = spt.Refresh()
if (err == nil) {
token := spt.Token
}
```
* Replace the `APPLICATION_SECRET` with the `password` value from previous section.
#### Client Certificate
```Go
certificatePath := "./example-app.pfx"
certData, err := ioutil.ReadFile(certificatePath)
if err != nil {
return nil, fmt.Errorf("failed to read the certificate file (%s): %v", certificatePath, err)
}
// Get the certificate and private key from pfx file
certificate, rsaPrivateKey, err := decodePkcs12(certData, "")
if err != nil {
return nil, fmt.Errorf("failed to decode pkcs12 certificate while creating spt: %v", err)
}
spt, err := adal.NewServicePrincipalTokenFromCertificate(
*oauthConfig,
applicationID,
certificate,
rsaPrivateKey,
resource,
callbacks...)
// Acquire a new access token
err = spt.Refresh()
if (err == nil) {
token := spt.Token
}
```
* Update the certificate path to point to the example-app.pfx file which was created in previous section.
#### Device Code
```Go
oauthClient := &http.Client{}
// Acquire the device code
deviceCode, err := adal.InitiateDeviceAuth(
oauthClient,
*oauthConfig,
applicationID,
resource)
if err != nil {
return nil, fmt.Errorf("Failed to start device auth flow: %s", err)
}
// Display the authentication message
fmt.Println(*deviceCode.Message)
// Wait here until the user is authenticated
token, err := adal.WaitForUserCompletion(oauthClient, deviceCode)
if err != nil {
return nil, fmt.Errorf("Failed to finish device auth flow: %s", err)
}
spt, err := adal.NewServicePrincipalTokenFromManualToken(
*oauthConfig,
applicationID,
resource,
*token,
callbacks...)
if (err == nil) {
token := spt.Token
}
```
#### Username password authenticate
```Go
spt, err := adal.NewServicePrincipalTokenFromUsernamePassword(
*oauthConfig,
applicationID,
username,
password,
resource,
callbacks...)
if (err == nil) {
token := spt.Token
}
```
#### Authorization code authenticate
``` Go
spt, err := adal.NewServicePrincipalTokenFromAuthorizationCode(
*oauthConfig,
applicationID,
clientSecret,
authorizationCode,
redirectURI,
resource,
callbacks...)
err = spt.Refresh()
if (err == nil) {
token := spt.Token
}
```
### Command Line Tool
A command line tool is available in `cmd/adal.go` that can acquire a token for a given resource. It supports all flows mentioned above.
```
adal -h
Usage of ./adal:
-applicationId string
application id
-certificatePath string
path to pk12/PFC application certificate
-mode string
authentication mode (device, secret, cert, refresh) (default "device")
-resource string
resource for which the token is requested
-secret string
application secret
-tenantId string
tenant id
-tokenCachePath string
location of oath token cache (default "/home/cgc/.adal/accessToken.json")
```
Example acquire a token for `https://management.core.windows.net/` using device code flow:
```
adal -mode device \
-applicationId "APPLICATION_ID" \
-tenantId "TENANT_ID" \
-resource https://management.core.windows.net/
```

/*
Package autorest implements an HTTP request pipeline suitable for use across multiple go-routines
and provides the shared routines relied on by AutoRest (see https://github.com/Azure/autorest/)
generated Go code.
The package breaks sending and responding to HTTP requests into three phases: Preparing, Sending,
and Responding. A typical pattern is:
req, err := Prepare(&http.Request{},
token.WithAuthorization())
resp, err := Send(req,
WithLogging(logger),
DoErrorIfStatusCode(http.StatusInternalServerError),
DoCloseIfError(),
DoRetryForAttempts(5, time.Second))
err = Respond(resp,
ByDiscardingBody(),
ByClosing())
Each phase relies on decorators to modify and / or manage processing. Decorators may first modify
and then pass the data along, pass the data first and then modify the result, or wrap themselves
around passing the data (such as a logger might do). Decorators run in the order provided. For
example, the following:
req, err := Prepare(&http.Request{},
WithBaseURL("https://microsoft.com/"),
WithPath("a"),
WithPath("b"),
WithPath("c"))
will set the URL to:
https://microsoft.com/a/b/c
Preparers and Responders may be shared and re-used (assuming the underlying decorators support
sharing and re-use). Performant use is obtained by creating one or more Preparers and Responders
shared among multiple go-routines, and a single Sender shared among multiple sending go-routines,
all bound together by means of input / output channels.
Decorators hold their passed state within a closure (such as the path components in the example
above). Be careful to share Preparers and Responders only in a context where such held state
applies. For example, it may not make sense to share a Preparer that applies a query string from a
fixed set of values. Similarly, sharing a Responder that reads the response body into a passed
struct (e.g., ByUnmarshallingJson) is likely incorrect.
Lastly, the Swagger specification (https://swagger.io) that drives AutoRest
(https://github.com/Azure/autorest/) precisely defines two date forms: date and date-time. The
github.com/Azure/go-autorest/autorest/date package provides time.Time derivations to ensure
correct parsing and formatting.
Errors raised by autorest objects and methods will conform to the autorest.Error interface.
See the included examples for more detail. For details on the suggested use of this package by
generated clients, see the Client described below.
