Infrastructure Software

Hi all,


........
debug1: Next authentication method: publickey
debug1: Trying private key: /export/home/user1/.ssh/identity
debug1: Trying private key: /export/home/user1/.ssh/id_rsa
debug1: Trying private key: /export/home/user1/.ssh/id_dsa
debug1: Next authentication method: keyboard-interactive
Password:

====================================
I would like to ask for open SSH, by default it will look for .ssh/identity, .ssh/id_rsa, .ssh/id_dsa
Can we change it?

In my previous company, I was using some kind of commercial SSH, which is using .ssh2 instead of .ssh.
Inside the .ssh2, it will have a identification file, for example:
IdKey <keyfilename>

However, it is not in open SSH, so can I said there are not supported the identification files?



Actually my problem is here:
Application team required 4 users to use public key authentication to a same user on the remote server.
However, these 4 users are sharing a same $HOME, so $HOME/.ssh/id_rsa can only own by 1 ID.
As we know, public key authentication required the private key to have a permission of 600, hence there only have 1 user can use the private key

I have try to copy the same key named as .ssh/id_rsa_a, .ssh/id_rsa_b, .ssh/id_rsa_c, .ssh/id_rsa_d.......

but it only look for ".ssh/id_rsa" only


Any people can help on this?
