FYI.

I was having a problem with Samba on fedora core 4 running SE Linux. I couldn't map the home directories, and kept getting the following syslog message:

Code:
Oct 18 01:07:50 zippy smbd[2748]:   .Unable to open passdb database. 
Oct 18 01:07:50 zippy smbd[2748]: [2005/10/18 01:07:50, 0] passdb/pdb_smbpasswd.c:startsmbfilepwent(279)

Code:
# touch /.autorelabel ; init 6
Then I started to get these errors:

Code:
Oct 17 22:27:58 zippy smbd[2975]:   '/data/mydocs' does not exist or is not a directory, when connecting to [mydocs] 
Oct 17 22:29:40 zippy smbd[2975]: [2005/10/17 22:29:40, 0] smbd/service.c:make_connection_snum(615) 
Oct 17 22:29:40 zippy smbd[2975]:   '/data/mydocs' does not exist or is not a directory, when connecting to [mydocs]

This is my smb.conf configuration

The thread http://www.linuxquestions.org/questi...hreadid=335899 gives the following solutions, but it doesn't work on home directories that are on a partition other than /home.

Solution 1 (temporary; won't survive a re-boot):

Issue the command:

[root]# setsebool samba_enable_home_dirs=1

Solution 2 (might survive a reboot; I didn't actually try this one):

[root]# setsebool -P samba_enable_home_dirs=1

Solution 3 (survives a reboot):

This is the solution I ultimately settled on. Go to the /etc/selinux/targeted directory. Create a text file called booleans.local, and put the "samba_enable_home_dirs=1" line in it (without the quotes, of course).

Solution 4 (surives a reboot, but removes all SELinux protection):

Edit /etc/selinux/config. Change the line SELINUX=enforcing to SELINUX=permissive or SELINUX=disabled.
I tried solution #3. (I don't want to jeopardize my SELinux on a wireless network)

I looked at the context of the / directory and saw that the contexts of /data and /home were different.

Code:

[root@zippy tmp]#
So I just changed /data to match the context of /home and it works just fine. Hooray!



Code:
[root@zippy tmp]# chcon -t home_root_t /data/{/code]
[/code]
