module: ldap_passwd
|
|
short_description: Set passwords in LDAP.
|
|
description:
|
|
- Set a password for an LDAP entry. This module only asserts that
|
|
a given password is valid for a given entry. To assert the
|
|
existence of an entry, see M(community.general.ldap_entry).
|
|
notes:
|
|
- The default authentication settings will attempt to use a SASL EXTERNAL
|
|
bind over a UNIX domain socket. This works well with the default Ubuntu
|
|
install for example, which includes a cn=peercred,cn=external,cn=auth ACL
|
|
rule allowing root to modify the server configuration. If you need to use
|
|
a simple bind to access your server, pass the credentials in I(bind_dn)
|
|
and I(bind_pw).
