Go to Applications → Add
Create a new application:
- Name: BlueMind
- URL: https://bluemind.example.com
- Description: Complete collaborative messaging
- Icon: Choose the BlueMind icon

2. Configure SAML2

In the Authentication tab
Select SAML2
Configure the following parameters:
- Entity ID: https://[your-smartlink].link.vaultys.org/[appid]
- ACS URL: https://bluemind.example.com/saml2/SSO
- NameID Format: emailAddress
- App ID: [appid] (automatically generated unique identifier)

3. Retrieve the metadata

Note the following URLs:

    def __init__(self, base_url, sso_token):
        self.base_url = base_url
        self.session = requests.Session()
        self.session.headers.update({
            'Authorization': f'Bearer {sso_token}',
            'Content-Type': 'application/json'
        })

            f'{self.base_url}/api/user/{email}'
        )
        return response.json()
    
    def create_calendar_event(self, user_email, event_data):
        """Create a calendar event"""
        response = self.session.post(
            f'{self.base_url}/api/calendar/{user_email}/events',
            json=event_data
        )
        return response.json()

            json=email_data
        )
        return response.json()

BlueMind Webhooks

// Endpoint for BlueMind webhooks
app.post('/webhook/bluemind', async (req, res) => {
  const { event, data } = req.body;
  
  switch(event) {
    case 'user.login':
      await logUserAccess(data);
      break;
    
    case 'mail.received':
      await processIncomingMail(data);
      break;

Configuration Testing

1. Web Connection Test

Log out of BlueMind
Go to https://bluemind.example.com
Click on SSO Login
Authenticate via SmartLink
Verify access to the messaging system

2. IMAP/SMTP Test with SSO

# IMAP Test with OAuth2
openssl s_client -connect bluemind.example.com:993 -crlf
A01 AUTHENTICATE XOAUTH2 [base64_encoded_token]

# SMTP Test with OAuth2
openssl s_client -connect bluemind.example.com:587 -starttls smtp
AUTH XOAUTH2 [base64_encoded_token]

3. Client Testing

Thunderbird: Automatic configuration via Autodiscover
Outlook: ActiveSync and OAuth2 support
Mobile: BlueMind iOS/Android applications with SSO

Troubleshooting

Error "SAML authentication failed"

Issue: SAML authentication fails

Solution:

Verify that the Entity ID is [appid]
Check the X.509 certificate format
Check the logs: /var/log/bluemind/core.log
Test with SAML-tracer (browser extension)

Error "User not found"

Issue: SSO user not found

Solution:

Ensure that automatic provisioning is enabled
Make sure the email matches the BlueMind domain
Check the email attribute in the SAML assertion

Group Synchronization Issue

Issue: Groups are not correctly mapped

Solution:

<!-- Correct format for SAML groups -->
<saml:Attribute Name="memberOf">
  <saml:AttributeValue>CN=bluemind-admins,OU=Groups,DC=example,DC=com</saml:AttributeValue>
  <saml:AttributeValue>CN=bluemind-users,OU=Groups,DC=example,DC=com</saml:AttributeValue>
</saml:Attribute>

ActiveSync Error with SSO

Issue: ActiveSync not working with SSO

Solution:

Generate an application password for ActiveSync
Use OAuth2 if supported by the client
Configure modern authentication in Exchange/ActiveSync
