LDAPD(8)

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.

HISTORY
The ldapd program first appeared in OpenBSD 4.8.

CAVEATS
ldapd is not yet fully LDAPv3 compliant.

Database files are not expected to work across architectures and may not work across versions.
