Pushkar,

If you want to use GDAL for your TIFF files you need to configure and
build MapServer without direct TIFF support or the direct TIFF support
will get used in preference.  I have been sort of intending to change
the configure to disable TIFF support (unless explicitly requested during
the configure) if GDAL is configured in, but haven't gotten around to it.

Best regards,
