Hello all, I have this strange situation:
a) user jane on one system transfers her public DSA key to account john at a given remote host. it works. jane accesses john's account without typing a password. b) now the same user jane transfers her public DSA key to account mary at the _same_ remote host. it does not work. she get's prompted for a passord (she get's access by typing mary's password) my guess is that there must be some difference between john and mary accounts. I can not realise what it is (shell is bash on both). Can anyone help ? Please find bellow the output of "ssh -vvv ...." for both situations. Thank you Joao ======================== success situation ==================== OpenSSH_5.3p1 Debian-3ubuntu7, OpenSSL 0.9.8k 25 Mar 2009 debug1: Reading configuration data /etc/ssh/ssh_config debug1:
