Problem downloading blob with url

[djoncour_]

Hello,

I have a problem when I want to download a blob with a url like this on my website

localhost:8080/nuxeo/nxfile/default/*/blobholder:0/*

I use authentification CAS2_AUTH and ANONYMOUS_AUTH. But when I am connect to this for the first time, I can't download it but a windows is prompt with differents repositories. And when I come back on website i can download it. But I want to download it without a windows is prompted for the first login.

This is my configuration

<extension
    target="org.nuxeo.ecm.platform.ui.web.auth.service.PluggableAuthenticationService"
    point="chain">
    <authenticationChain>
        <plugins>
            <plugin>BASIC_AUTH</plugin>
            <plugin>PORTAL_AUTH</plugin>
            <plugin>CAS2_AUTH</plugin>
            <plugin>ANONYMOUS_AUTH_FOR_CAS2</plugin>
        </plugins>
    </authenticationChain>
</extension>

It's very strange because if I delete the AUNONYMOUS_AUTH and If I connect to my wrbsite without connected on nuxeo I can download it. But if I let this line I have the problem that I describe on top of this topic.

And my log I have this following error but I don't want to give anonymous read rights for this document

ERROR [org.nuxeo.ecm.core.api.CoreSession] Permission 'Read' is not granted to 'guest' on document
ERROR [org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/nuxeo]] Session event listener threw exception

ava:89)
at org.nuxeo.ecm.platform.web.common.exceptionhandling.NuxeoSecurityExceptionHandler.handleException(NuxeoSecurityExceptionHandler.java:71)

I really don't ubderstand what is my problem, If my configuration is bad or something like that. Thanks for your help.

Hello Thierry,

Now, I use the 5.6 version with HF29, nuxeo-platform-login-cas2-5.6.jar and the same configuration which is written in this ticket [https://jira.nuxeo.com/browse/NXP-12491][1]. Now I can download a document by a direct link with Firefox and Chrome but not with IE 9 10 and 11. When Itry to download one, I automatically redirect on logout CAS page. But with IE 8 it works fine.

Thank you for your help
