MAIL::FOLDER::GETRIG(3x)

NAME
mail::folder::getRights - Read access control list

SYNOPSIS

#include <libmail/mail.H>
class myCallback : public mail::callback {
public:
    void success(std::string msg);
    void fail(std::string msg);
};

folder->getRights(myCallback &callback, std::list<std::pair<std::string, std::string> > &rights);

USAGE

This function implements folder access control lists (ACLs). Access control lists define who is allowed to do certain operations on a folder, or on messages in the folder. Folder ACLs are implement only for IMAP accounts on IMAP servers that implement access control lists. This function will fail if folder is not a folder on an IMAP server that supports access control lists.

This function obtains folder's entire access control list. If this function succeeds (this function may fail if the requesting client does not have the required access to the folder), rights will be initialized to an array of identifier/accessrights tuples.

  Identifier

Not all servers support every one of the following access control list identifiers. See the server's documentation to check which access control list identifiers are implemented by the server:

“anonymous”, or “anyone”
    This identifier refers to universal access rights given to everyone, including anonymous users (if supported by server).

“authuser”
    Same as “anyone”, except for anonymous users. If the server does not implement anonymous access, then “anonymous”, “anyone”, and “authuser” are equivalent.

“owner”
    The owner of the mailbox that contains the folder.

“administrators”
    Any member of a group that's defined as an administrator group, in an implementation-defined way.

“user=username”
    A single system user, identified by username.

“group=groupname”
    Any system user that's part of a group identified by groupname. Groups are created and managed by IMAP server-specific tools. See the server's documentation for information on creating and managing groups (if the groups are even implemented by the server in the first place).

“-identifier”
    An access control list identifier may be prefixed by a “-”, which refers to a “negative right”. Negative rights explicitly revoke the associated access rights from the identifier instead of granting the right.

    Negative rights are not implemented by all servers. See the server's documentation to check if the server implements negative access rights.

    Note

    username and groupname must specified using the UTF-8 character set.

  Access rights

At this time, the following access rights are supported:

“a”
    Administrator access: view and change folder access control lists.

“c”
    Create subfolders.

“e”
    Expunge deleted messages from the folder.

“i”
    Insert, or add messages to the folder.

“l”
    List, or view the folder's existence. If a folder does not have the “l” access right, the server will not include this folder when it's asked to list all folders in the folder directory. However, if the “r” access right is present, the folder may be opened if the folder's name is known.

“r”
    Read, or open the folder. An attempt to open the folder will fail without the “r” access right, even if the folder's name is known.

“p”
    “Post messages” to the folder. This access right is currently listed in the ACL specification; however its intention is not clear, and most servers do not do anything useful with this access right. It is listed here for information purposes only.

“s”
    Allow changing the read/unread status of messages in the folder. The server will not automatically clear the unread message status flag on messages after they are read, or let this status flag be explicitly changed, without the “s” access right.

“t”
    Allow tagging of messages as deleted or undeleted. The server will prohibit changing the messages' deleted message status flag without the “t” access right.

“w”
    Allow changing the draft, replied, and marked message status flags. The server will not allow changes to these flags without the “w” access right.

“x”
    Allow this folder to be removed. The server will not this folder to be deleted without the “x” access right.

RETURN CODES AND CALLBACKS

The application must wait until callback's success or fail method is invoked. The success method is invoked when this request is succesfully processed. The fail method is invoked if this request cannot be processed. The application must not destroy callback until either the success or fail method is invoked.

    Note

    callback's fail method may be invoked even after other callback methods were invoked. This indicates that the request was partially completed before the error was encountered.
