Authentication Fails to ServiceManager Follow

This case relates to the following cases:

1. You have ServiceManager installed on DMZ.

2. You can login to ServiceManager from internal network

3. You can access ServiceManager from external network (and access services), BUT you can't login to ServiceManager, you get error: Authentication failed.

Other use case:

Login to ServiceManager fails although you have configured all the settings properly.

This issue happens due to the fact that the external url is not identified, or being blocked in the internal network.

Solution 1 fail to access from External Network:

Login to ServiceManager from your internal network.

Go to Admin->System Management->System Properties

uncomment the following line, and set your server's port (for example 7001):

AUTHENTICATION_SERVER = http://localhost:7001

click on the button Update Properties.

Solution 2 Error in Authentication:

Go to the user's Home directory (Windows: C:\Users\<userName>, Linux: \home\<user>)

Go to the directory: ServiceManager 

edit servicemanager.properties file

uncomment the following line, and set your server's FQDN or localhost (depends the error):

AUTHENTICATION_SERVER = http://<FQDN>:<port>
