It indicates the presence of an ACL (file access control list), as
documented in "info coreutils 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 a security
     context, but no other alternate access method.

     A file with any other combination of alternate access methods is
     marked with a `+' character.

See "man getfacl" and "man 5 acl" for more information on ACLs.
