Compatibility with OG module?

Hi,

0) log in as site admin
1) Create a gallery as standard group post, with password

After 0~1, I can see the gallery on the group homepage ( the page by og_ghp_ron )

2) switch to non-admin, and on the group homepage:
a) gallery node title disappear
b) gallery content (a folder image with lock on top) disappear
c) author, created, add comment links, remain.

Any ideas?

Thanks.
