If the Mozilla Firefox Internet browser is used, the Windows Integrated Login, also called Single Sign-on, can be allowed using the NTLM authentication procedure in order to access the UMSettings without having to log in again.
To do this, enter "about:config" in the address line of the Mozilla Firefox Internet browser and confirm with Return.
If you agree with the message that appears, confirm it.
Filter for "network.automatic-ntlm-auth.trusted-uris" via the text field FILTER.
Edit the setting by double-clicking and enter the primary address of the server.
For example, if you access the UMSettings via "http://Server/XPhoneConnect/UMSettings/", enter "http://Server".
If multiple addresses are used, they must be separated by a comma.
