This property gives the users the possibility to prevent an account from being used. This flag does not change the validity of the account.

A disabled account can never be put online.

The AccountManager SHOULD allow this property to be set on invalid accounts, but MUST NOT attempt to put invalid accounts online even if they become Enabled.

Some protocols, like XMPP and SIP, are used by various different user-recognised brands, such as Google Talk and Ovi by Nokia. On accounts for such services, this property SHOULD be set to a string describing the service, which MUST consist only of ASCII letters, numbers and underscores, and start with a letter (matching the requirements for Protocol_Name). For the jabber protocol, one of the following service names should be used if possible:

• google_talk (for Google's IM service)
• ovi_chat (for Ovi's IM service)
• facebook (for Facebook's IM service)
• lj_talk (for LiveJournal's IM service)
• windows_live (for Windows Live Messenger IM service)

For the IRC protocol, the network name (freenode, gimpnet, etc.) can be used if relevant.

The Icon property SHOULD be set to a corresponding brand-specific icon name, if possible. In the future, this property may be used as an index into additional service-specific customizations. If this property is the empty string (or missing), the service is determined by the protocol name (either because this is a single-service protocol like msn, or because this is just a generic jabber or sip account without specific branding).

This property MAY be set, if appropriate, when calling CreateAccount. Updating this property will fail on externally-stored accounts whose StorageRestrictions include Cannot_Set_Service.

A map from connection manager parameter names (as in the ConnectionManager interface) to their values. This property includes only those parameters that are stored for this account, and SHOULD only include those parameters that the user has explicitly set.

This property cannot be altered using org.freedesktop.DBus.Properties.Set(); use UpdateParameters instead.

The presence status that this account should have if it is brought online.

Setting this property MUST NOT actually change the account's status until the next time it is (re)connected for some reason.

The value of this property MUST be one that would be acceptable for RequestedPresence, with the additional restriction that the Connection_Presence_Type MUST NOT be Offline.

Either the object path of the Connection to this account, or the special value '/' if there is no connection.

If this object path is not '/', the Connection's well-known bus name can be derived from this object path by removing the first '/' and replacing subsequent '/' characters with '.'.

If the last connection to this account failed with an error, the D-Bus error name of that error; otherwise, the empty string. The account manager is expected to set this by observing the Connection.ConnectionError and Connection.StatusChanged signals.

If ConnectionError is received before the connection disconnects, its first argument should be used to set this property; otherwise, the Reason argument of StatusChanged should be converted to a suitable D-Bus error name.

Whenever the Connection connects successfully, this property should be reset to the empty string.

If the last connection to this account failed with an error, a mapping representing any additional information about the last disconnection; otherwise, the empty map. The keys and values are the same as for the second argument of Connection.ConnectionError.

Whenever the Connection connects successfully, this property should be reset to the empty map.

The requested presence for this account. When this is changed, the account manager should attempt to manipulate the connection manager to make CurrentPresence match RequestedPresence as closely as possible. It should not be saved to any sort of persistent storage.

When the account manager automatically connects an account, it must signal this by setting the RequestedPresence to the same thing as the AutomaticPresence.

The Connection_Presence_Type in this property MUST NOT be Unset, Unknown or Error.

If true, a change to the presence of this account is in progress.

Whenever RequestedPresence is set on an account that could go online, or whenever an account with a non-offline RequestedPresence becomes able to go online (for instance because Enabled or Usable changes to True), ChangingPresence MUST change to True, and the two property changes MUST be emitted in the same PropertiesChanged signal, before the Set method returns.

When the account manager succeeds or fails in changing the presence, or the connection disconnects due to an error, ChangingPresence MUST change to False as part of the same PropertiesChanged signal.

The normalized user ID of the local user on this account (i.e. the value of the SelfID property for an active connection).

It is unspecified whether this user ID is globally unique.

If this value is not known yet (which will always be the case for accounts that have never been online), it will be an empty string.

It is possible that this value will change if the connection manager's normalization algorithm changes, although this SHOULD be avoided.

A list of the object paths of formerly-used accounts which are superseded by this one.

If the Account Manager implementation performs an account migration automatically, it SHOULD set this property. If a client performs an account migration, it SHOULD set this property via via the Properties argument of CreateAccount when creating the migrated account. In either case, the value SHOULD include the old account's path, and every path from the old account's Supersedes property.
