short_description: Add or remove multiple LDAP attribute values
|
||||
description:
|
||||
- Add or remove multiple LDAP attribute values.
|
||||
notes:
|
||||
- This only deals with attributes on existing entries. To add or remove
|
||||
whole entries, see M(community.general.ldap_entry).
|
||||
- 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).
|
||||
- For I(state=present) and I(state=absent), all value comparisons are
|
||||
performed on the server for maximum accuracy. For I(state=exact), values
|
||||
have to be compared in Python, which obviously ignores LDAP matching
|
||||
rules. This should work out in most cases, but it is theoretically
|
||||
possible to see spurious changes when target and actual values are
|
||||
semantically identical but lexically distinct.
