> It can be obtained by "legal" residents, although I don't think legal residents can get passports on the basis of their aadhar number. Aadhar fundamentally solves the problem of illegal residents and nefarious foreign agents getting valid credentials...
Please see the documentation accepted for proof of date of birth [1] and proof of address [2] to get an Indian passport. Both accept a valid Aadhaar number that can be verified. And an Aadhaar number can be obtained through an introducer without providing documents. Since the government has also claimed that there are fake PAN cards, fake drivers licenses, etc., an Aadhaar number can be obtained by providing those too. It's not as difficult to get a passport and claim citizenship as you think. Aadhaar, in a convoluted way, makes this a lot easier. It does not solve the problem in any way.
As for rations and subsidies, you can read the links tryprasannan has posted or visit Rethink Aadhaar [3] to understand how these claims are erroneous and how people are getting excluded.
