NAME

doveadm-acl - Manage Access Control List (ACL)

SYNOPSIS

doveadm [-Dv] [-f formatter] acl command [OPTIONS] [ARGUMENTS]

DESCRIPTION

The doveadm acl COMMANDS can be used to execute various Access Control List related actions.

OPTIONS

Global doveadm(1) options:

-D

Enables verbosity and debug messages.

-f formatter

Specifies the formatter for formatting the output. Supported formatters are:

flow

prints each line with key=value pairs.

pager

prints each key: value pair on its own line and separates records with form feed character (^L).

tab

prints a table header followed by tab separated value lines.

table

prints a table header followed by adjusted value lines.

-o setting=value

Overrides the configuration setting from /etc/dovecot/dovecot.conf and from the userdb with the given value. In order to override multiple settings, the -o option may be specified multiple times.

-v

Enables verbosity, including progress counter.

This command uses by default the output formatter table.

Command specific options:

-A

If the -A option is present, the command will be performed for all users. Using this option in combination with system users from userdb { driver = passwd } is not recommended, because it contains also users with a lower UID than the one configured with the first_valid_uid setting.

When the SQL userdb module is used make sure that the iterate_query setting in /etc/dovecot/dovecot-sql.conf.ext matches your database layout. When using the LDAP userdb module, make sure that the iterate_attrs and iterate_filter settings in /etc/dovecot/dovecot-ldap.conf.ext match your LDAP schema. Otherwise doveadm(1) will be unable to iterate over all users.

-F file

Execute the command for all the users in the file. This is similar to the -A option, but instead of getting the list of users from the userdb, they are read from the given file. The file contains one username per line.

-S socket_path

The optionaqs argument is either an absolute path to a local UNIX domain socket, or a hostname and port (hostname:port), in order to connect a remote host via a TCP socket.

This allows an administrator to execute doveadm(1) mail commands through the given socket.

-u user/mask

Run the command only for the given user. Itaqs also possible to use aq*aq and aq?aq wildcards (e.g. -u *@example.org).
When neither the -A option, nor the -F file option, nor the -u user was specified, the command will be executed with the environment of the currently logged in user.

ARGUMENTS

id

The id (identifier) is one of:

*

group-override=group_name

*

user=user_name

*

owner

*

group=group_name

*

authenticated

*

anyone (or anonymous, which is an alias for anyone)

The ACLs are processed in the precedence given above, so for example if you have given read-access to a group, you can still remove that from specific users inside the group.
Group-override identifier allows you to override usersaq ACLs. Probably the most useful reason to do this is to temporarily disable access for some users. For example:

user=timo rw
group-override=tempdisabled

Now if timo is a member of the tempdisabled group, he has no access to the mailbox. This wouldnaqt be possible with a normal group identifier, because the user=timo would override it.

mailbox

The name of the mailbox, for which the ACL manipulation should be done. Itaqs also possible to use the wildcard characters dq*dq and/or dq?dq in the mailbox name.

right

Dovecot ACL right name. This isnaqt the same as the IMAP ACL letters, which arenaqt currently supported. Here is a mapping of the IMAP ACL letters to Dovecot ACL names:

l -> lookup

Mailbox is visible in mailbox list. Mailbox can be subscribed to.

r -> read

Mailbox can be opened for reading.

w -> write

Message flags and keywords can be changed, except rsSeen and rsDeleted.

s -> write-seen

rsSeen flag can be changed.

t -> write-deleted

rsDeleted flag can be changed.

i -> insert

Messages can be written or copied to the mailbox.

p -> post

Messages can be posted to the mailbox by dovecot-lda, e.g. from Sieve scripts.

e -> expunge

Messages can be expunged.

k -> create

Mailboxes can be created/renamed directly under this mailbox (but not necessarily under its children, see ACL Inheritance in the wiki).
Note: Renaming also requires the delete right.

x -> delete

Mailbox can be deleted.

a -> admin

Administration rights to the mailbox (currently: ability to change ACLs for mailbox).

COMMANDS

acl add

doveadm acl add [-u user|-A|-F file] [-S socket_path] mailbox id right [right ...]

Add ACL rights to the mailbox/id. If the id already exists, the existing rights are preserved.

acl debug

doveadm acl debug [-u user|-A|-F file] [-S socket_path] mailbox

This command can be used to debug why a shared mailbox isnaqt accessible to the user. It will list exactly what the problem is.

acl delete

doveadm acl delete [-u user|-A|-F file] [-S socket_path] mailbox id

Remove the whole ACL entry for the mailbox/id.

acl get

doveadm acl get [-u user|-A|-F file] [-S socket_path] [-m] mailbox

Show all the ACLs for the mailbox.

acl recalc

doveadm acl recalc [-u user|-A|-F file] [-S socket_path]

Make sure the useraqs shared mailboxes exist correctly in the acl_shared_dict.

acl remove

doveadm acl remove [-u user|-A|-F file] [-S socket_path] mailbox id right [right ...]

Remove the specified ACL rights from the mailbox/id. If all rights are removed, the entry still exists without any rights.

acl rights

doveadm acl rights [-u user|-A|-F file] [-S socket_path] mailbox

Show the useraqs current ACL rights for the mailbox.

acl set

doveadm acl set [-u user|-A|-F file] [-S socket_path] mailbox id right [right ...]

Set ACL rights to the mailbox/id. If the id already exists, the existing rights are replaced.
