[Samba] Strange automount problem with samba & LDAP

Following code segment pasted from vfstest works when I connect 
anonymously (or root) does the automount, but when I connect as a user 
it does not work.
It wold be nice if someone could explain the difference between 
anonymous login or root login and normal login, where they don't share 
the same code. It seems to me that automount can not get right 
information when loging as a user to samba (may be a extra null 
character appended). any help will be appreciated.

        vfs.conn = conn_new();
        for (i=0; i < 1024; i++)
                vfs.files[i] = NULL;
        test=SMB_VFS_STAT(vfs.conn, "/home/stf4/yusuf", &mystatus);
        if (test == -1) {
                DEBUG(0,("make_connection_snum: stat unsuccessfull!\n"));
        else {
                DEBUG(0,("make_connection_snum: stat successfull.\n"));
                if (S_ISDIR(st.st_mode))
                        DEBUG(0,("make_connection_snum: Directory!!\n"));
                        DEBUG(0,("make_connection_snum: Not
