setting uid,gid on samba share

[Jon Reynolds]

I used to be able to issue the command:
mount -t smbfs -o username=jonr,password=password,uid=jon,gid=jon
//server/share /mnt/shared

This has always worked before but now on freebsd4.8 the -o is no longer
an option. How can I connect and set the uid,gid? I have read the
mount_smbfs man page and see an -O option but I don't understand how to
make it do what I want.

Can someone help me finger this out?
