From "info ls":
Following the file mode bits is a single character that specifies
whether an alternate access method such as an access control list
applies to the file. When the character following the file mode
bits is a space, there is no alternate access method. When it is
a printing character, then there is such a method.
GNU `ls' uses a `.' character to indicate a file with an SELinux
security context, but no other alternate access method.
A file with any other combination of alternate access methods is
marked with a `+' character.
In order to make files located on one server can be accessied by other servers, SELinux should be disabled. In order to disable SELinux, refer to How to Disable SELinux.
