GetErrorLongString for error 20071

[Jim Matthews]

A user reports getting the error message "Unknown Error20071" from a 
beta release of Fetch 4.0.2, using KfM 4.0 on Mac OS X.  The error 
string is generated by GetErrorLongString.  It appears that 20000 is 
the base error code for KClient calls, and so 20071 is (from krb.h):

#define         AD_NOTGT   71	/* Don't have tgt */

Shouldn't GetErrorLongString generate a nicer message?

Also, is there some obvious reason why a user would get that error code?
