I got some log message I can't explain. when I log in to a server it says:

[2011/07/12 14:20:41.784580,  0] passdb/passdb.c:627(lookup_global_sam_name)
User frvdamme with invalid SID S-1-5-21-2863620551-4077714424-203869783-5020 in

It's a standalone file server, no domain, and the password backend is
(open)ldap. Samba is version 3.5.6 on Debian 6.0. Using the server
actually works well, I can allow/deny access to shares based on groups
etc. But I can't see user names in the security tab in Windows
explorer (I only see the sid). As a consequence, I also can't set
permissions from Windows.

In fact, to be more precise, users and groups that exist locally on
the system *do* show up in the security tab. Those in ldap do not.
