Example of ldap.conf:

 

# Your LDAP server. Must be resolvable without using LDAP.
# Multiple hosts may be specified, each separated by a
# space. How long nss_ldap takes to failover depends on
# whether your LDAP client library supports configurable
# network or connect timeouts (see bind_timelimit).
#host 127.0.0.1

# The distinguished name of the search base.
base dc=mydomain,dc=net

# Another way to specify your LDAP server is to provide an
# uri with the server name. This allows to use
# Unix Domain Sockets to connect to a local LDAP Server.
uri ldap://ldap1.mydomain.net/ ldap://ldap2.mydomain.net/ ldap://ldap3.mydomain.net/
#uri ldap://127.0.0.1/
#uri ldaps://127.0.0.1/
#uri ldapi://%2fvar%2frun%2fldapi_sock/
# Note: %2f encodes the ‘/’ used as directory separator

# The LDAP version to use (defaults to 3
# if supported by client library)
#ldap_version 3

# The distinguished name to bind to the server with.
# Optional: default is to bind anonymously.
#binddn cn=useracct,dc=mydomain,dc=net

# The credentials to bind with.
# Optional: default is no credential.
#bindpw secret

# The distinguished name to bind to the server with
# if the effective user ID is root. Password is
# stored in /etc/ldap.secret (mode 600)
#rootbinddn cn=manager,dc=mydomain,dc=net

# The port.
# Optional: default is 389.
#port 389

# The search scope.
#scope sub
#scope one
#scope base

# Search timelimit
#timelimit 30
timelimit 120

# Bind/connect timelimit
#bind_timelimit 30
bind_timelimit 120

# Reconnect policy: hard (default) will retry connecting to
# the software with exponential backoff, soft will fail
# immediately.
#bind_policy hard

# Idle timelimit; client will close connections
# (nss_ldap only) if the server has not been contacted
# for the number of seconds specified below.
#idle_timelimit 3600
idle_timelimit 3600

# Filter to AND with uid=%s
#pam_filter objectclass=account

# The user ID attribute (defaults to uid)
#pam_login_attribute uid

# Search the root DSE for the password policy (works
# with Netscape Directory Server)
#pam_lookup_policy yes

# Check the ‘host’ attribute for access control
# Default is no; if set to yes, and user has no
# value for the host attribute, and pam_ldap is
# configured for account management (authorization)
# then the user will not be allowed to login.
#pam_check_host_attr yes

# Check the ‘authorizedService’ attribute for access
# control
# Default is no; if set to yes, and the user has no
# value for the authorizedService attribute, and
# pam_ldap is configured for account management
# (authorization) then the user will not be allowed
# to login.
#pam_check_service_attr yes

# Group to enforce membership of

# Group member attribute
#pam_member_attribute uniquemember

# Specify a minium or maximum UID number allowed

# Template login attribute, default template user

# in user’s entry)
#pam_login_attribute userPrincipalName
#pam_template_login_attribute uid
#pam_template_login nobody

# HEADS UP: the pam_crypt, pam_nds_passwd,
# and pam_ad_passwd options are no
# longer supported.
#
# Do not hash the password at all; presume
# the directory server will do it, if
# necessary. This is the default.
#pam_password clear

# Hash password locally; required for University of
# Michigan LDAP server, and works with Netscape
# Directory Server if you’re using the UNIX-Crypt

# RFC2307bis naming contexts
# Syntax:
# nss_base_XXX        base?scope?filter
# where scope is {base,one,sub}
# and filter is a filter to be &’d with the
# default filter.
# You can omit the suffix eg:
# nss_base_passwd    ou=People,
# to append the default base DN but this
# may incur a small performance impact.
