DOVEADM-ACL(1) Dovecot DOVEADM-ACL(1)

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:

Enables verbosity and debug messages.
Specifies the formatter for formatting the output. Supported formatters are:
prints each line with key=value pairs.
prints each key: value pair on its own line and separates records with form feed character (^L).
prints a table header followed by tab separated value lines.
prints a table header followed by adjusted value lines.
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.
Enables verbosity, including progress counter.

This command uses by default the output formatter table.

Command specific options:

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.

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.
The option's 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.

Run the command only for the given user. It's also possible to use '*' and '?' 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

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 users' 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 wouldn't be possible with a normal group identifier, because the user=timo would override it.

The name of the mailbox, for which the ACL manipulation should be done. It's also possible to use the wildcard characters "*" and/or "?" in the mailbox name.
Dovecot ACL right name. This isn't the same as the IMAP ACL letters, which aren't currently supported. Here is a mapping of the IMAP ACL letters to Dovecot ACL names:
Mailbox is visible in mailbox list. Mailbox can be subscribed to.
Mailbox can be opened for reading.
Message flags and keywords can be changed, except \Seen and \Deleted.
\Seen flag can be changed.
\Deleted flag can be changed.
Messages can be written or copied to the mailbox.
Messages can be posted to the mailbox by dovecot-lda, e.g. from Sieve scripts.
Messages can be expunged.
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.
Mailbox can be deleted.
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 isn't 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 user's 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 user's 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.
