This error occurs when you attempt to sign in to the GN4 browser, but your credentials are not recognized. The 'item1' typically looks like as <domainname>\username.

There may be several causes of this error: some can be related to a bad configuration of the system, and other on bad credentials.

Possible causes

1.The GN4 system is configured to use Windows authentication, but the user logged onto this computer is not listed in the GN4 database, or not exactly with the shown data as in 'item1'.

2.The GN4 system is not configured to use Windows authentication, but in the PortalConfig.xml (typically in config\Global\GN4_Tark4_Common), the LoginMode is not set to FormPersistent.

To correct this error

1.Check your credentials with the domain System Administrator.

2.See the instructions in Browser doesn't show login form.
