    NIS to LDAP (N2L)
        If the /var/yp/NISLDAPmapping configuration file is present, the NIS
        server operates in NIS to LDAP (N2L) mode. In this mode, NIS maps are
        stored in a new set of DBM files, prepended by the LDAP_ prefix, at
-       /var/yp/domainename. These files are used as a cache backed by
+       /var/yp/domainname. These files are used as a cache backed by
        information from an LDAP server. Additional DBM files are created in
        the same directory to hold the cache's TTL values.
 
 
        N2L mode enables NIS clients to be supported in an LDAP environment.
