.SH LIMITATIONS
The practice storing hashed passwords in userPassword violates
hashed passwords has been defined (RFC 3112), but is not yet
implemented in
.BR slapd (8).
+.TP
+It should also be noted that the behavior of
+.BR crypt (3)
+is platform specific.
.SH "SECURITY CONSIDERATIONS"
Use of hashed passwords does not protect passwords during
protocol transfer. TLS or other eavesdropping protections
-should be inplace before using LDAP simple bind. The
-hashed password values should be protected as if they
+should be in\-place before using LDAP simple bind.
+.TP
+The hashed password values should be protected as if they
were clear text passwords.
