NAME

ypldap.conf — LDAP YP map daemon configuration file

DESCRIPTION

The ypldap(8) daemon provides YP maps using LDAP as a backend.

The ypldap.conf config file is divided into the following main sections:

Macros: User-defined variables may be defined and used later, simplifying the configuration file.
Global Configuration: Global settings for ypldap(8).
Directories: LDAP Directory specific parameters.

MACROS

Much like cpp(1) or m4(1), macros can be defined that will later be expanded in context. Macro names must start with a letter, digit, or underscore, and may contain any of those characters. Macro names may not be reserved words (for example, domain). Macros are not expanded inside quotes.

For example:

fixed_gecos="Pulled from LDAP"

fixed attribute gecos $fixed_gecos

GLOBAL CONFIGURATION

Global settings concern the main behaviour of the daemon.

domain string: Specify the name of the NIS domain ypldap.conf will provide.
interval seconds: Specify the interval in seconds at which the whole directory will be pulled from LDAP.
provide map string: Specify a map that should be provided by ypldap.conf The currently implemented maps are: passwd.byname, passwd.byuid, group.byname, group.bygid.
cafile filename: Load CA certificates from the specified file to validate the server certificate. If not specified, CA certificates will be loaded from /etc/ssl/cert.pem.

DIRECTORIES

Directories are used to describe the LDAP schema and help ypldap.conf convert LDAP entries to passwd(5), master.passwd(5), and group(5) lines. Each directory section consists of a declaration of the directory server name and a set of directives describing how entries from the directory are used to construct YP map entries.

directory hostname [port port] [tls] {...}

Defines a directory by hostname and optionally port number. If the tls argument is not specified, no transport-level security will be used. Valid options are:

tls: Use STARTTLS to negotiate TLS, by default on port 389.
ldaps: Connect with TLS enabled, by default on port 636.

Valid directives for directories are:

attribute name maps to string

Map the passwd(5), master.passwd(5), or group(5) attribute to the LDAP attribute name supplied.

basedn string

Use the supplied search base as starting point for the directory search.

groupdn string

Use the supplied search base as starting point for the directory search for groups. If not supplied, the basedn value will be used.

bindcred string

Use the supplied credentials for simple authentication against the directory.

binddn string

Use the supplied Distinguished Name to bind to the directory.

fixed attribute attribute string

Do not retrieve the specified attribute from LDAP but instead set it unconditionally to the supplied value for every entry.

group filter string

Use the supplied LDAP filter to retrieve group entries.

list name maps to string

Map the passwd(5), master.passwd(5), or group(5) attribute to the LDAP attribute name supplied. A list creates a comma separated list of all the LDAP attributes found.

Valid attributes are:
