HTTP Basic Authentication method has to be enabled on the StoreFront server for credential injection operations that you do with StoreBrowse utility.
If you have HTTP store, and when you try connecting to the store using the utility for enumerating Apps/Desktops or Launch the published Apps/Desktops, then the credential injection via command line option is unsupported. As a workaround, you can use the external AuthManager module which gets triggered when you do not provide credential via command line
StoreBrowse currently support NetScaler Gateway configured with only single store configured on the StoreFront server.
Credential Injection in StoreBrowse will work only if NetScaler Gateway is configured with Single Factor Authentication.
The command line options Username (-U), Password (-P) and Domain (-D) of the Storebrowse utility are case-sensitive and must be in upper case only.
