Problem disabling slide authorization
When working on SimpleFileStore, it was easy to disable Slide security by setting org.apache.slide.security=false in slide.properties. However, I do want to be able configure basic webapp security using security constraints on paths and HTTP methods. But I do not want to manage users and roles within slide. So I have slide configured with security=false, SimpleFileStore, TransientSecurityStore, and TransientLockStore for my store implementations, all user and role definitions removed from Domain.xml and basic auth configured in my web.xml for the path to the webdav servlet. With this config, I can connect via webdav, log in and browse. However, I cannot create files or folders, copy, move, delete The problem that I am running in to is that Methods (MkcolMethod for example), still try to authorize the current principal. If the principal is null, things work fine b/c SecurityImpl returns SubjectNode.UNAUTHENTICATED and slide lets this continue. However, if the principal is not null (it is not when the webapp makes the user log in), SecurityImpl.getPrincipal( ) tries to retrieve an object for that user resulting in an ObjectNotFoundException. This looks like hard behavior to change (unfortunately). AbstractWebDavMethod creates the SlideToken with the user principal in run( ) using req.getUserPrincipal(). I haven't traced through the other methods to see if/how the user principal is used. It looks like copy/delete/put/move/mkcol (at least) all have issues related to this. Any thoughts? What I am trying to do seems like a pretty common use case. Is there a good way to address this need? I'm hoping I've missed something simple.

Re: Problem disabling slide authorization
With a little digging, I appear to have a solution. It looks like you can set your own implementation of Security in Domain.xml with parameter name=acl_semantics/parameter. I created an AllowAllSecurityImpl that does its best to be okay with everything. The only method I really implemented is getPrincipal(SlideToken token) which returns SubjectNode.UNAUTHORIZED if there is no user principal in the SlideToken, or a SubjectNode with the principal name as the path if there is a principal. So I configure my domain to load it with: configuration parameter name=acl_semanticsorg.apache.slide.store.file.AllowAllSecurityImpl/parameter /configuration http://cvs.sourceforge.net/viewcvs.py/photospace/slidespace/WEB-INF/src/org/apache/slide/store/file/ Seems to work for me. Any comments or gotchas I may have missed?

Re: ldap configuration
Hello Miguel,
I'm also working with the JNDIPrincipalStore. I think the problem is the way the file
based stores are implemented. You have set the security and lock store to be a file
based store. Earlier I've tried to separate data of an ExtendedStore by spreading it
over 6 file based stores each using different directories. It didn't work.
The error could lie in AbstractXMLResourceDescriptor.encodeObject() (if you don't use
an old version of Slide):
Element aElementObjectNode = new Element(objectnode);
if (object != null) {
aElementObjectNode.setAttribute(classname, object.getClass().getName());
aElementObjectNode.setAttribute(uri, object.getUri());
if (object instanceof LinkNode) {
aElementObjectNode.setAttribute(linkTo, ((LinkNode) object).getLinkedUri());
}
} else {
// for null locks
aElementObjectNode.setAttribute(classname, null);
aElementObjectNode.setAttribute(uri, uri.toString());
}
aElementObjectNode.addContent(createBindings(children, child,
object.enumerateBindings()));
aElementObjectNode.addContent(createBindings(parents, parent,
object.enumerateParentBindings()));
aElementObjectNode.addContent(createElements(links, link,
object.enumerateLinks()));
return aElementObjectNode;
First there is distinguished between an object being null or not. After that there is
always tried to access the child bindings of object - even if it's null.
Try replacing your security and lock store by a JDBCStore. For me it works that way.

FW: Need Help for Caching issue in slide 2.0 (PLESAE DO HELPFUL)
Hi, I am using slide 2.0 binary with Database store. What I have observed is when slide application starts it initializes the Domain.xml File and accordingly it creates the contents (metadata) in the database. Now when I connect through network place and create some files or folders, sometimes that files/folders are not immediately reflected in the network place (windows explorer). I have to refresh and then only it gets displayed in explorer. What I found is it is not firing the queries everytime. One more strange behaviour I found is sometimes when I copy one file (say xyz.sql) and paste it In another folder, the file is displayed as a WebFolder and even on refresh it is displaying it as a folder. But when I restart the slide application I can see the same xyz.sql as a file. So are these issues related to any kind of caching in slide or windows xp network place.

Re: Problem disabling slide authorization
So after letting this sit for just a little bit, it strikes me that this may be considered a bug in SecurityImpl (or the calling Method implementations). The Methods are calling getPrincipal() so that they can set the owner metadata in the node being created. When security is off but webapp security is on, there is a Principal in the CredentialsToken but it does not exist in the store. So you get an ObjectNotFoundException. If SecurityImpl finds a Principal in the CredentialsToken but not in the NodeStore, why not return a SubjectNode with the principal name as the path? Or do this if slide security is disabled?
