Connect DODS Server

[NicoSIG]

I would like to connect Mapserver to a DODS Server.
latitude and longitude variables must be named 'lat' and 'lon', and on my
Server, they're named 'LATITUDE' and 'LONGUITUDE'.

By using AIS mechanism, I wrote a DAS file with an Alias.

Here is my mapfile:
MAP
...
CONFIG DODS_AIS_FILE
"/home/alboran/logiciels/apache/htdocs/mtreguer/cartoweb3/projects/sextant_test/server_conf/sextant/dods/ais.xml"
...
LAYER
    NAME "serveur_dods"
    TYPE POINT
    CONNECTIONTYPE OGR
     CONNECTION
"DODS:http://rhsism11.ifremer.fr:8080/dap4cor/dap4cor-coriolis?lat,lon,POSITION_QC&lat>47&lat<50&lon>-6&lon<0"

    DATA "location"
    STATUS DEFAULT
.......


Here is ais.xml file :
<?xml version="1.0" encoding="US-ASCII" standalone="no"?>
<!DOCTYPE ais SYSTEM "http://xml.opendap.org/ais/ais_database.dtd">
<ais xmlns="http://xml.opendap.org/ais">
   
  <entry>
    <primary regexp="http://rhsism11.ifremer.fr:8080/dap4cor*"/>
    <ancillary rule="fallback"
url="/home/alboran/logiciels/apache/htdocs/mtreguer/cartoweb3/projects/sextant_test/server_conf/sextant/dods/Coriolis.das"/>
  </entry>
  
</ais>

And this is Coriolis.das:

Attributes {
  Alias lat location.LATITUDE;
  Alias lon location.LONGITUDE;
}


but the system return an error:

Error in msOGRFileOpen(): Open failed for OGR connection
`DODS:http://rhsism11.ifremer.fr:8080/dap4cor/dap4cor-coriolis?lat,lon,POSITION_QC&lat>47&lat<50&lon>-6&lon<0'.
Error fetching DAS or DDS:
Error parsing the text on line 1 at or near: 
The descriptor object returned from the dataset was null.
Check that the URL is correct.

it seems that aliases are not considered.
how to resolve this problem ??
