ssh connection using cygwin

I am trying to connect with my remote linux server using cygwin+ssh but the authentication fails with no apparent reason. I have successfully setup another connnection to github successfully and I have followed the same process, this is why I am stopped here

$ ssh -v [email protected]
OpenSSH_6.0p1, OpenSSL 1.0.1c 10 May 2012

debug1: No more authentication methods to try.
Permission denied (publickey).

I have made the standard stuff but I cannot solve the problem. These are the commands I have used to generate the private/public keys. I have then copied the public key to the server

$ ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/home/xxxtta/.ssh/id_dsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/xxxtta/.ssh/id_dsa.
Your public key has been saved in /home/xxxtta/.ssh/id_dsa.pub

thank you for your help

EDIT: I have made the same procedure using MINGW and it works (I am able to connect). Something is definitely going wrong with cygwin in my system

Problem probably lies in user name. If you login remotely user name is case sensitive. You must write user name exactly how it was defined in Windows.

You might try -vvv instead of -v to increase the verbosity.
Also, check that the file permissions are set properly. See Adding public key to ~/.ssh/authorized_keys does not log me in automatically

Copy id_dsa.pub to your remote server. 

# scp .ssh/id_dsa.pub dude@remotemachine

On remote server:

# cat id_dsa.pub >> ~/.ssh/authorized_keys
