ldapd(8) - OpenBSD manual pages

NAME

ldapd — Lightweight Directory Access Protocol (LDAP) daemon

SYNOPSIS

ldapd [-dnv] [-D macro=value] [-f file] [-r directory] [-s file]

DESCRIPTION

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.

AUTHENTICATION

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.
