DMAcc Configuration Service Provider

Send Feedback

This configuration service provider handles the OMA DM DMAcc management object that stores the OMA DM server-specific settings. These settings are collectively referred to as an OMA DM account. The DMAcc node is the parent to all OMA DM accounts nodes.

Note   Access to this Configuration Service Provider is determined by Security roles. Because OEMs and Mobile Operators can selectively disallow access, ask them about the availability of this Configuration Service Provider. For more information about roles, see Security Roles and Default Roles for Configuration Service Providers.

The following image shows the management object used by OMA DM.

The following table shows the default settings for DMAcc. The default security role maps to each subnode unless specific permission is granted to the subnode.

Format	Node
Roles allowed to query and update setting	Operator Manager Operator TPS

• DMAcc
  The root node for DMAcc object. The following table shows the default settings.

  Format	Node
  Access Type	Get
  Occurs	One
  Scope	Permanent

• DMAcc/x
  A placeholder for one or more SyncML DM account nodes. The "x" is a unique identifier for the OMA DM account settings, making each DMAcc/x node the unique parent node for an account. This node name is assigned by the server at bootstrap. If the device is bootstrapped with the w7 Application Configuration Service Provider, then the value for x is a hash of the server-ID.

  The following table shows the default settings.

  Format	Node
  Access Type	Add, Get, Delete, Replace
  Occurs	Zero or more
  Scope	Dynamic

• DMAcc/x/Addr
  Stores various addresses. The type of address stored is specified by the value of the AddrType node.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/AddrType
  Specifies the format and interpretation of the x/Addr node value. The value is encoded as inline string, as specified in the following table:

  Address Type	Value	Description
  HTTP	1	URL (See RFC2396)

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/PortNbr
  Specifies the port number to use for the current bearer, if applicable. This must be a decimal number and must fit within the range of a 16-bit unsigned integer.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	Zero or one
  Scope	Dynamic

• DMAcc/x/ConRef
  Points to connectivity information that is stored elsewhere in the device. This is used to locate connectivity information that is stored separately from the SyncML DM management object.

  This should provide a logical link to an existing connectivity object anywhere in the device.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/ServerId
  The server identifier for the current OMA DM account. This value is set during bootstrap.

  Note   After the ServerId is set, it cannot be changed in a regular OMA DM session.

  Note   In a server trigger, the client treats ServerID as UTF-8 encoding, instead of US-ASCII character. UTF-8 is the super set of US-ASCII.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete
  Occurs	One
  Scope	Dynamic

• DMAcc/x/ServerPW
  Holds the password or secret that the server uses to authenticate itself to the client.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/ServerNonce
  Stores the next nonce that the server will use to authenticate itself to the client. Nonce refers to a 'number used once'. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in 'repeat attacks'.

  The following table shows the default settings.

  Format	bin
  Access Type	Add, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/UserName
  Stores the name of the user or device. This information is used in OMA DM authentication.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/ClientPW
  Holds the password or secret that the client uses to authenticate itself to the server.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/ClientNonce
  Stores the next nonce that the client will use to authenticate itself to the server. Nonce refers to a 'number used once'. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in 'repeat attacks'.

  The following table shows the default settings.

  Format	bin
  Access Type	Add, Delete, Replace
  Occurs	One
  Scope	Dynamic

• DMAcc/x/AuthPref
  (Optional) A string-valued parameter who's possible values are the names of the various SyncML authentication types. For example, syncml:auth-md5. If this node is present, the client uses this authentication type when connecting to the server. The use of this node reduces the number of round trips between client and server that would be caused by authentication challenges.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	Zero or one
  Scope	Dynamic

• DMAcc/x/Name
  (Optional) Stores the name for the current SyncML DM account.

  The following table shows the default settings.

  Format	chr
  Access Type	Add, Get, Delete, Replace
  Occurs	Zero or one
  Scope	Dynamic

• DMAcc/x/Ext
  Stores extended parameters

  The following table shows the default settings.

  Format	Node
  Access Type	Get
  Occurs	Once
  Scope	Dynamic

• DMAcc/x/Ext/Microsoft
  Stores Microsoft-specific parameters

  The following table shows the default settings.

  Format	Node
  Access Type	Get
  Occurs	Once
  Scope	Dynamic

• DMAcc/x/Ext/Microsoft/Role
  Specifies the role mask that the DM session runs with when it communicates with the server.

  If this parameter is not present, the DM session is given the role mask of the DM session that the server is created.

  The following table shows the default settings.

  Format	chr
  Access Type	Get, Replace
  Occurs	Once
  Scope	Dynamic
