I am using objective-c for the first time.

My requirement is to authenticate the logged in user and find their SID.

In windows development we have a very few APIS, with the help of which we can find out the SID of the user.

My assumption is: there should be some functions in the cocoa framework which should tell us the SID of the user.

If there is no such feature, then how else should I try to find it?

Guide me on this.

    I think it’s a unique identifier for the device.

    This open source project helps you get that:

    UIDevice-with-UniqueIdentifier-for-iOS-5

    From the documentation:

    use [[UIDevice currentDevice] uniqueDeviceIdentifier] to retrieve the
    unique identifier (it’s a hash of your Bundle ID + MAC address)

    use [[UIDevice currentDevice] uniqueGlobalDeviceIdentifier] to
    retrieve a global unique identifier (it’s a hash of the MAC address,
    used for tracking between different apps).
