问题
I am using grails 2.1.0. I have installed spring-security-core plugin.
When I create user it is creating it. But when I try to login then it shows:
"Sorry, we were not able to find a user with that username and password."
And there is also another fact that is when I use the same password for different user it does not save password with similar encoded value like for user 1 I have used password 123 which is saved in database like this
d535ce213a0e8e4f9e724af47c46eea409ef401c03617b749da618a82890d743
and for user 2 I also used password 123 and this time it is saved like this
0849ea79a2c1bca057ded06c3053fb5bc5d7ba52b50982e73e44894d4f3e0aa6
I don't understand. Can anyone please help me on this ?

回答1:
I think you are encoding your password twice, you already have encode() on beforeInsert in the domain, I think you need not to encode it again.
回答2:
Spring Security use hash of user password + a salt. Salt is used to defeat pre-computed rainbow table attacks that could otherwise be used to greatly improve the efficiency of cracking the hashed password database. See http://en.wikipedia.org/wiki/Salt_(cryptography)
For example, if we're using username as a hash, real value in database will be:
md5(user.password + '|' + user.username)
So for two different userw with same password:
- user: username: 'user1', password: 123
- user: username: 'user2', password: 123
you'll get two different values in database:
md5('user1|123')==975204d0650cc642730866d56f66b6fbmd5('user2|123')==aa12022115555842a7f80564940ae49d
So, if hacker have access to you database he cannot guess the password.
Spring Security uses same hashing function and salt for saving and loading user. And if it unable to find user it probably means that you've used different salt for initial save and for later load from the database. Make sure that you have same salt source, and it's not changing (like id field, that have null value when you just creating a new user)
