Jim, 

ISO 8589-1 and UTF-8 are the same in the ASCII range, i.e. for values
[0,127].  Unless your username or password includes non-ASCII characters,
I don't see how it's possible for the iconv conversion to present the
server with different strings.  If you want to make sure, you can expose
them in the log: delete the tdsdump_off() and tdsdump_on() lines at
src/tds/login.c:768 and rebuild.  I think if you re-run the tests, you'll
see the same login packet being sent.  (You need reinstall only FreeTDS. 
Score one for dynamic linking.) 

Other than that, I'm unfortunately stumped.  You're using db-lib in PHP;
you can confirm that db-lib can log in by trying bsqldb.  But I'm sure
that will work, too, which leads us back to why PHP can't log in, and I
just don't see any reason.  

This is a SQL Server account, yes, not a domain login?  Just trying to
narrow the scope.  Both should work just fine.  And just to eliminate the
possibility, try using TDS versions 7.0 and 4.2, too.  

Stumped in New York, and no snow, either.
