[Geoserver-users] How can I configure user name/password in geowebcache.xml for wmslayers?

Jukka_Rahkonen · December 19, 2012, 3:01pm

Hi,

As I wrote some hours ago, you can use only one username/password in geowebcache.xml. Because in your case you want to connect with several WMS services using different usernames and passwords it just does not work. This limitation could be worth making a feature request. Meanwhile you'd better investigate some proxy systems and/or try to find funding for contracting the development work.

You have already tried Geoserver as a proxy but perhaps you quit too easily. How about securing cascaded layers so that only your GWC user has rights for them? I do know that InteProxy works too.

Aihe: Re: [Geoserver-users] How can I configure user name/password in
geowebcache.xml for wmslayers?

I am planning to stop to use Cascading WMS layers approach now.
if I use this approach,I have to publish the layer locally in geoserver.
But I don't want to publish the layer in geoserver.

So, How can directly access the external service layer using geowebcache.xml
file configuration with specific username and password for each layer?
Because I am plan to access the layer directly without local geoserver.

Thanks.

I thought geowebcache.xml file support multiple username and password for
each layer url.
So that I asked again and again.

Now I got it clearly,so I skip that multiple username and password for each
layer url.

Now I will use cascaded layers or InteProxy .

I don't think so about cascaded layers for my GWC user.

But I will test with both approach in my app.

I have the feeling it is still not completely clear, hence copies from my
geowebcache.xmls:

1st case: one password for all layers at the beginning of the
geowebcache.xml:

<?xml version="1.0" encoding="utf-8"?>
<gwcConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://geowebcache.org/schema/1.2.2
http://geowebcache.org/schema/1.2.4/geowebcache.xsd"
xmlns="http://geowebcache.org/schema/1.2.2">
  <version>1.2.4</version>
  <backendTimeout>240</backendTimeout>
  <cacheBypassAllowed>false</cacheBypassAllowed>
  <httpUsername>cm85</httpUsername>
  <httpPassword>xxxx</httpPassword>
.......

2nd case you have different accounts for different layers:

you put it into the <wmsLayer> tag as below
...........
      <wmsUrl>
        <string>http://imagestest.land.vic.gov.au/ecwp/ecw_wms.dll</string>
      </wmsUrl>

<wmsLayers>ZTEST_ALG_VIC-LANDCOVER_2009DEC14_AIR_VIS_50CM_VG94</wmsLayers>
      <httpUsername>cm85</httpUsername>
      <httpPassword>xxxx</httpPassword>
      <expireCache>-2</expireCache>
      <backendTimeout>240</backendTimeout>
      <cacheBypassAllowed>false</cacheBypassAllowed>
      <queryable>false</queryable>
    </wmsLayer>

Obviously the layers could go to different servers.

3rd case you have different <wmsLayers> with different permits in one
<wmsLayer> tag.

Does not work.

Cheers

Christian

do you mean,the layers could go to different servers if my geowebcache.xml
like this?.

<layers>
    <wmsLayer>
      <name>kd:sverigekartan</name>
      <httpUsername>U1</httpUsername>
      <httpPassword>P1</httpPassword>

<wmsUrl><string>http://maps.lantmateriet.se/allmannakartor/wms/v1</string></wmsUrl>
    </wmsLayer>
    <wmsLayer>
      <name>kd:topowebbkartan</name>
        <httpUsername>U2</httpUsername>
       <httpPassword>P2</httpPassword>

<wmsUrl><string>http://maps-eval.lantmateriet.se/topowebbfast/wms/v1</string></wmsUrl>
    </wmsLayer>
    <wmsLayer>
      <name>kd:orto</name>
        <httpUsername>U1</httpUsername>
        <httpPassword>P1</httpPassword>

<wmsUrl><string>http://maps.lantmateriet.se/ortophoto/wms/v1</string></wmsUrl>
    </wmsLayer>
    <wmsLayer>
      <name>gde:Gazetter</name>

<wmsUrl><string>http://localhost:8081/geoserver/wms?layers=gde:Gazetter</string>
</wmsUrl>
    </wmsLayer>
    <wmsLayer>
      <name>0</name>
      <httpUsername>U3</httpUsername>
       <httpPassword>P3</httpPassword>

<wmsUrl><string>http://nvkarta.vic-metria.nu/ArcGIS/services/NVKarta/MapServer/WMSServer?</string></wmsUrl>
    </wmsLayer>
</layers>

Thanks

Thanks lot.
<layers>
          <wmsLayer>
                        <name>kd:sverigekartan</name>
                        <httpUsername>U1</httpUsername>
                        <httpPassword>P1</httpPassword>

<wmsUrl><string>http://maps.lantmateriet.se/allmannakartor/wms/v1</string></wmsUrl>
          </wmsLayer>
          <wmsLayer>
                        <name>kd:topowebbkartan</name>
                          <httpUsername>U2</httpUsername>
                         <httpPassword>P2</httpPassword>

<wmsUrl><string>http://maps-eval.lantmateriet.se/topowebbfast/wms/v1</string></wmsUrl>
          </wmsLayer>

</layers>

This above approach is working in my application.Now I can set unique
username and password for each and every layer.

I haven't the time to try it but I think the order is relevant. At least
that is what I foggily recall and more importantly that is what my
XML-editor tells me. So, please see the example below. I think <wmsUrl>
after <httpUsername> and <httpPassword> doesn't work.

<wmsLayer>
      <name>SATELLITE_TEST_Google</name>
      <metaInformation>
        <title>Aerial Landcover Vic</title>
        <description>Melbourne April 2008</description>
      </metaInformation>
      <mimeFormats>
        <string>image/jpeg</string>
      </mimeFormats>
      <gridSubsets>
        <gridSubset>
          <gridSetName>EPSG:900913</gridSetName>
          <extent>
            <coords>

      <wmsUrl>

Sorry for late response.
Order is not a problem.It should work.
I have tried using my layer
like <wmsUrl> after <httpUsername> and <httpPassword>
and
<wmsUrl> before <httpUsername> and <httpPassword>.
