samba - Jul 2010 - Alternative to Samba by Link***?

Hello

I vaguely remember reading an article months ago about some fork or
altnernative provider of Samba called something like Link***.

The Wikipedia article on Samba only mentions TNG.

http://en.wikipedia.org/wiki/Samba_%28software%29

Does someone know what I'm refering to and could tell me more?

Thank you.

Found it: It's Likewise

http://en.wikipedia.org/wiki/Likewise_Open

Is it a complement to Samba or a full replacement? What's the
added-value of Likewise?

Thank you.

Dear samba team,
 	Please help me on the below issue.

    I have connected a samba share from my device to my  windows XP
machine . that samba share has ACL support enabled . 
1) The shared folder names is "user1" and the user  name I logged into
samba share is also user1.

2) I have created a text file , and sub folder in the samba share from
my windows PC.

3) I can change write permission of the owner "user1" and the group
"users"  , and Everyone from the security -> advanced settings
->

4) for the sub folder I cannot change the permissions for the owner
"user1" , I can change for the group "users" and Everyone
also.

whenever I tried to disable the "Write attributes" and "Write
extended
attributes" , it is simply ignoring the changes and again showing
"full
control" in advance security windows.


Please suggest how to handle this?.
here is my samba.conf

Dear samba team,
 please help me in understanding these.

1) in samba posix_acls.c why samba always setting the READ access for
the file and READ and WRITE access for directory ?
----------
case S_IRUSR:
		/* Ensure owner has read access. */
		pace->perms |= S_IRUSR;
		if (is_directory)
			pace->perms |= (S_IWUSR|S_IXUSR);
		and_bits = unix_perms_to_acl_perms(and_bits, S_IRUSR,
S_IWUSR, S_IXUSR);
		or_bits = unix_perms_to_acl_perms(or_bits, S_IRUSR,
S_IWUSR, S_IXUSR);

-----------
2) I have connected a samba share from the device onto my windows xp
machine.. when I tried modify subfolder owner  write permissions , it is
simply ignoring that and setting the write permission again.

Thanks
Suresh
