Description Lutz Lange 2008-02-07 15:05:18 UTC 
Description of problem:
setting public_content_rw_t on a samba share does not allow writing with smbclient.

Version-Release number of selected component (if applicable):
samba-3.0.25b-0.el5.4
selinux-policy-2.4.6-104.el5

How reproducible:
create a samba share
make it wirteable
adjust file permissons
adjust selinux context to public_content_rw_t
call smbclient //server/share
try > mkdir test

change selinux context to samba_share_t
try again -> success

Expected results:
public_content_rw_t should be writeable
Comment 1 Daniel Walsh 2008-02-07 15:56:21 UTC 
You need to turn on the smbd boolean.

setsebool -P allow_smbd_anon_write 1
Comment 2 Lutz Lange 2008-02-07 17:04:06 UTC 
This means i should allow annonymous writes? 
I dont write annonymously. I connect as student with password.

$ smbclient -U student //station8/share

Sorry to have been too unspecific.

I can attach my whole config, if you like.
Comment 3 Daniel Walsh 2008-02-07 17:18:13 UTC 
No this boolean just allows smbd to write to files labeled public_content_rw_t.

From SELinux point of view this is anonymous.  (public_content_t) was originally
ftp_anon_t.

So you are not allowing anonymous writes from an Samba point of view, just
SELinux view of the world.
