Lightweight Directory Access Protocol
(LDAP) daemon

ldapd is a daemon which implements version
3 of the LDAP protocol.
A running ldapd process can be controlled
using the ldapctl(8) utility.
The options are as follows:
-D
macro=value- Define macro to be set to
value on the command line. Overrides the definition
of macro in the configuration file.
-d- Do not daemonize and log to
stderr.
-f
file- Use file as the configuration file, instead of the
default /etc/ldapd.conf.
-n- Configtest mode. Only check the configuration file for validity.
-r
directory- Store and read database files in directory, instead
of the default /var/db/ldap.
-s
file- Specify an alternative location for the socket file.
-v- Produce more verbose output. A second
-v together
with the -d flag produces debug traces of decoded
BER messages on stderr.
ldapd can authenticate users via simple
binds or SASL with the PLAIN mechanism.
When using simple binds, the bind DN entry must exist in a
namespace and have a userPassword attribute. The
following formats of the userPassword attribute are
recognized:
{SHA}digest- Verify the password against the SHA-1 digest.
{SSHA}digest- Verify the password against the salted SHA-1 digest.
{CRYPT}hash- Verify the password against the
crypt(3)
hash.
{BSDAUTH}username- Use BSD Authentication with the given username and
authentication style “auth-ldap”. This is similar to using
SASL PLAIN authentication with username as the
authentication ID.
{BSDAUTH}username#class- Same as above, but overrides the login class.
Without a prefix, the userPassword
attribute is compared literally with the provided plain text password.
When using SASL binds, the authentication ID should be a valid
username for BSD Authentication.
For plain text passwords to be accepted, the connection must be
considered secure, either by using an encrypted connection, or by using the
secure keyword in the configuration file.

The ldapd program first appeared in
OpenBSD 4.8.
ldapd is not yet fully LDAPv3
compliant.
Database files are not expected to work across architectures and
may not work across versions.
