4. Troubleshooting Tips

The following are the few errors that can be encountered during Password Manager Pro login via Azure SAML SSO. All of those can be resolved by following the respective troubleshooting steps that follow:

1. Error: AADSTS75011

Issue: Password Manager Pro uses a Password for SAML authentication, but some browsers like Edge stores the previous session and use X509 certificates with Azure IDP, causing validation failure due to authRequest mismatch.

Solution:

To resolve this, remove AuthnRequest elements from Azure AD by:

1. Navigating to <Password_Manager_Pro_installation_directory>\conf folder.
2. Adding the system property saml.AuthnContextRequired=false to system_properties.conf file with administrator privilege.
3. Restarting the Password Manager Pro server for changes to take effect.

2. Error: AADSTS750054

Issue: Incorrect configuration of SAML Single-Sign-On and SAML assertion consumer URL in the enterprise application.

Solution:

Update respective URLs with the valid input:

1. Open the Password Manager Pro enterprise application in Microsoft Azure.
   
2. Go to Single Sign On under Manage.
3. Ensure correct URLs are set for the Sign On URL (Password Manager Pro web portal URL - https://hostname:port) and Reply URL (SAML assertion consumer URL - https://hostname:port/saml2).
   

3. Error: AADSTS7000218

Issue: SAML authentication failure due to the Password Manager Pro enterprise application being created as a confidential client, preventing username/password authentication.

Solution:

Configure enterprise app as PUBLIC client:

1. Log into the Microsoft Azure portal, and open the Password Manager Pro enterprise application.
   
2. Under Manage, click Authentication.
3. Change from Web to Public client/Native.
   

Note: If you have multiple redirect URLs, you need to make the necessary changes in all of them.

4. Select Default Client Type as YES.
5. Ensure required API permissions are granted and consent is given under the Permissions section.

4. Error: AADSTS75005 

Issue: Azure IdP doesn't support HTTPS REDIRECT binding protocol.

Solution:

Enable HTTP POST binding protocol:

1. In the Password Manager Pro console, go to Admin >> Authentication >> SAML Single Sign-On.
   
2. Choose Configure IdP information manually under the Configure Identity Provider Details section.
   
3. Change the Protocol Binding to HTTP-POST, then save the changes.
   

5. Error: ADSTS50105

Issue: The user lacks access to PMP/Password Manager Pro app in Azure AD.

Solution:

Ensure the user is assigned to the Password Manager Pro enterprise application. The user must belong to an assigned group or be directly assigned to the Password Manager Pro enterprise application. Refer to the relevant help section for steps to assign users to the app.

By following these steps, you can effectively troubleshoot and resolve common login errors when using Password Manager Pro with Azure SAML SSO.

6. Error: [com.adventnet.passtrix.saml.SAMLResponseValidator]|[SEVERE]|[78]: SAML Signature could not be validated|
