Documentation about config files is confusing

[fnevgeny]

Hello,

The docs (e.g., https://gridcf.org/gct-docs/6.2/gridftp/admin/index.html#gridftp-config-overview), but also the man page says:

The configuration file for the GridFTP server is read from the following locations, in the given order. Only the first file found will be loaded:

* Path specified with the -c <configfile> command line option.
* $GLOBUS_LOCATION/etc/gridftp.conf
* /etc/grid-security/gridftp.conf

Which creates a false impression that if $GLOBUS_LOCATION is not defined, /etc/gridftp.conf will be read. But in fact it isn't the case:

gct/gridftp/server/src/globus_i_gfs_config.c

Lines 3067 to 3075 in b01606b

	tmp_gl = getenv("GLOBUS_LOCATION");
	if(tmp_gl)
	{
	rc = snprintf(tmp_str, PATH_MAX, "%s/etc/gridftp.conf", tmp_gl);
	if(rc > 0)
	{
	local_config_file = tmp_str;
	}
	}

Later, local_config_file does become (typically) /etc/gridftp.conf:

gct/gridftp/server/src/globus_i_gfs_config.c

Lines 3269 to 3272 in b01606b

	if(local_config_file == NULL && !argv_only)
	{
	globus_eval_path("${sysconfdir}/gridftp.conf", &local_config_file);
	}

However, this is only used for setting environment

gct/gridftp/server/src/globus_i_gfs_config.c

Line 3119 in b01606b

rc = globus_l_gfs_config_load_envs_from_file(local_config_file);

But contrary to global_config_file, it is NOT parsed by globus_l_gfs_config_load_config_file().

Most confusing, in the log gridftp then happily reports that /etc/gridftp.conf was used...
