Per user webdav access to their home directories ?

[Frank Bonnet]

Hello

I would like to know if the following is possible with NGINX :

Setup a PERSONAL webdav access to our users, that is giving
access to their unix home directories thru a secure webdav.

If I understand well the main problem is the httpd process
has to switch to the user's identity after authentication ( LDAP )
to let him have RW access to his workspace.

Is it possible with the nginx beast ?
If yes, links to documentation would be welcome !

Thank you
