Log in to Google using the Identity Server¶

This page guides you through using MWARE IAM to log in to Google.

Configure Google¶

1. Access your domain's admin console via https://admin.google.com.

2. Click Security.

   Info

   Can't see the Security section? Click the MORE CONTROLS bar at the bottom and you can see the Security section.

   

3. Click Set up single sign-on (SSO) with a third party IdP.

   

4. Enter the following URLs to your third-party Identity Provider (IdP).

   • Sign-in page URL: https://<IS_HOSTNAME>:<IS_PORT>/samlsso

   • Sign-out page URL: https://<IS_HOSTNAME>:<IS_POST>/samlsso

   

5. Upload the Identity Server certificate:
   The certificate file must contain the public key for Google to verify the sign-in requests.

   1. Navigate to the <IS_HOME>/repository/resources/security directory via the terminal.

   2. Run the command given below to import the public certificate from the keystore to a .pem file.

      keytool -export -alias wso2carbon  -keystore wso2carbon.jks -storepass wso2carbon -file mycert.pem

      Info

      The mycert.pem file is created in the same directory mentioned in step a above. If you want to change the name of the file that is being generated, enter a preferred name instead of mycert in the above command.

   3. Click Replace certificate and upload the .pem file you just generated.

   4. Click Save.

Configure Email Address as the Username¶

1. Log in to the Management Console and click Claims > List > http://wso2.org/claims.

2. Click the Edit link corresponding to the Username claim and configure the Mapped Attribute property to mail.

   

3. Click Update to save the changes.

4. Open the <IS_HOME>/repository/conf/deployment.toml file.

5. Add the following configuration to enable email authentication.

   [tenant_mgt]
   enable_email_domain= true

6. Configure the following set of parameters in the userstore configuration, depending on the type of userstore you are connected to (LDAP/Active Directory/ JDBC).

   Parameter	Description
   UserNameAttribute	Set the mail attribute of the user. LDAP/Active Directory only [user_store] user_name_attribute = "mail"
   UserNameSearchFilter	Use the mail attribute of the user instead of cn or uid . LDAP/Active Directory only For example: In LDAP,[user_store] user_name_search_filter = "(&(objectClass=person)(mail=?))" In Active Directory, [user_store] user_name_search_filter = "(&(objectClass=user)(mail=?))"
   UserNameListFilter	Use the mail attribute of the user if necessary. LDAP/Active Directory only For example: In LDAP,[user_store] user_name_list_filter = "(&(objectClass=person)(!(sn=Service)))" In Active Directory, [user_store] user_name_list_filter = "(&(objectClass=user)(!(sn=Service)))"
   UsernameJavaScriptRegEx	Change this property that is under the relevant userstore manager tag as follows. This property allows you to add special characters like "@" in the username. [user_store] username_java_script_regex = '^[a-zA-Z0-9.-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$'
   UsernameJavaRegEx	This is a regular expression to validate usernames. By default, strings have a length of 5 to 30. Only non-empty characters are allowed. You can provide ranges of alphabets, numbers and also ranges of ASCII values in the RegEx properties. [user_store] username_java_regex = '^[a-zA-Z0-9.-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}'
   Realm configurations	The username must use the email attribute of the admin user. [super_admin] username = "admin@wso2.com" password = "admin" Note Before this configuration, the user having the username admin and password admin was considered the super administrator. The super administrator user cannot be deleted. After this configuration, the user having the username admin@wso2.com is considered the super administrator. The user having the username admin is considered as a normal administrator.

   Info

   • With these configuration users can log in to super tenant with both email username (alex@gmail.com) or non-email usernames (larry). However, for tenants, only email usernames are allowed. (tod@gmail.com@wso2.com).
   • You can configure email username without enabling the enable_email_domain property (step 5). Then users can log in to both the super tenant and the tenant using email and non-email usernames. However, super tenant users should always use @carbon.super at the end of usernames.

7. Restart the server.

Create the service provider¶

To register your application as a service provider in the MWARE IAM:

1. Log in to the MWARE IAM Management Console using administrator credentials.

2. Go to Main > Identity > Service Providers > Add.

3. Enter a Service Provider Name. Optionally, enter a Description.

4. Click Register.

SAML Configurations¶

Make the following changes to the created service provider.

1. Expand Inbound Authentication Configuration > SAML Configuration and click Configure.

2. Fill in the value for Issuer and Assertion consumer URL as shown below.

   Field	Value	Description
   Issuer	google.com	This is the <saml:Issuer> element that contains the unique identifier of the service provider.
   Assertion Consumer URL	https://www.google.com/a/<ENTER_YOUR_DOMAIN>/acs	This is the URL to which the browser should be redirected to after the authentication is successful. This is the Assertion Consumer Service (ACS) URL of the service provider. The identity provider redirects the SAML2 response to this ACS URL. However, if the SAML2 request is signed and SAML2 request contains the ACS URL, the Identity Server will honor the ACS URL of the SAML2 request.

3. Select Enable Response Signing to sign the SAML2 Responses returned after the authentication process.

4. Select Enable Attribute Profile and Include Attributes in the Response Always so that the the identity provider will always include the attribute values related to the selected claims in the SAML2 attribute statement.

5. Click Register.

Try it out¶

Now, you have successfully configured Google and MWARE IAM.

1. Create a user in MWARE IAM. Make sure that the same user exists in your Google domain.
   In this example, alex@wso2support.com is in the Google domain. Therefore, we need to create the same user in MWARE IAM.

   1. Log in to the MWARE IAM Management Console (https://<IS_HOST>:<PORT>/carbon) using administrator credentials (admin:admin).

2. Navigate to Main > Identity > Users and Roles > Add.

3. Click Add New User and enter username and password.  When adding a new user, use an email address as the username. Since it is not mandatory to assign a role to a user in this tutorial, click Finish.

4. Navigate to https://google.com/a/<ENTER_YOUR_DOMAIN>/acs and enter the email address (username) of the user you created.
   You are navigated to MWARE IAM's sign in screen.

5. Enter the username and password of the user you created.
   You are navigated to the G-Suite of that domain and you can select the application you need to use.
