Nowdays the best way to access remote Git repositories is through the HTTP transport. However most service still offer SSH connectivity, and there are times when you want to access different hosts with SSH identities different than the default one (id_rsa). Useful links

If you have an active ssh-agent that has your
id_rsa key loaded, then the problem is likely that ssh is offering that key first. Unfuddle probably accepts it for authentication (e.g. in sshd) but rejects it for authorization to access the company repositories (e.g. in whatever internal software they use for authorization, possibly something akin to Gitolite). Perhaps there is a way to add your personal key to the company account (multiple people are not sharing the same
corp_rsa public and private key files, are they?).
