You can protect a SharePoint server as a domain-based or a path-based multi-homing resource on Access Gateway. When you protect a SharePoint server on Access Gateway, you might see issues with rewriting if the published DNS name is not the same as the DNS name of the original server. Also, if you access SharePoint folder by using non-browser clients such as Microsoft Network Place, Nautilus in SUSE Linux Enterprise Server (SLES), or the MAC finder, you might see issues because these WebDAV clients do not support 302 redirection for authentication. You must modify the authentication procedure to prevent redirection on initial authentication or redirection to Identity Server when the user session expires.

in the NetIQ Access Manager 4.3 Administration Guide.
