What does the trailing "+" mean in file permission bits in Linux?

I used ls -a to list a file and got the following information:
sqyang@intel4-88: ls -a 123 -rwxr-xr-x+ 1 root lsf 16845584 Nov 25 21:38 123*
The file permission part is -rwxr-xr-x+. What does the + mean at the end?

The "+" indicates that there is an ACL (Access Control List) entry associated with the file. I don't know about Linux, but ACLs are used on Solaris too. See the manual pages for "getfacl" and "setfacl".

For files that have a default ACL or an access ACL that contains more than the three required ACL entries, the ls(1) utility in the long form produced by ls -l displays a plus sign ( + after the permission string.

when I type ls -la I get this familiar output...
drwxr-xr-x+ 38 kent staff 1292 Nov 6 11:09 .
drwxr-xr-x 5 root admin 170 Aug 14 14:11 ..

my question is about the file settings on the far left eg:
drwxr-xr-x+
I know that the first char 'd' means directory.
and the next 9 chars I understand as well (permissions)
but what is the final char in this field? (empty or + or @ )
