Username Does Not Display in XenMobile NetScaler Connector (XNC) Logs

Username is not displaying?? in the?? XenMobile NetScaler Connector (XNC) logs.
The username field in the XNC logs are empty, as displayed in the following screen shot:

When looking into the log files on XNC, you could verify that the user field is empty:

Note: When using certificate based authorization, the user name might not be visible in the User Name field because it is using the certificate instead of the username/password to authorize.

Ensure that the correct string for the “user” field is used in both callout policies (with and without deviceid):
HTTP.REQ.HEADER("authorization").AFTER_STR("Basic ").B64DECODE.BEFORE_STR(":").HTTP_URL_SAFE

Complete the following steps to resolve this issue:

1. Edit the string.

2. Add?? a new entry.

3. Remove the faulty one?? from each callout policy to make it work.

Note: The wizard would do this automatically, but there might be NetScaler versions in the field that do not have the wizards in place.

This generally occurs because of misspelling?? in the HTTP Callout policies.
The break occurs when there is NO SPACE after the alphabet c in?? Basic - For example, "Basic".
Ensure that you add a space after 'c' in Basic - "Basic " in the callout.
