When I am logged into my machine directly, I can do all git operations, and when prompted for a password, the password is accepted. When I ssh into the same box and run git operations on the same repos, the password is rejected.

Relevant section of .ssh/config looks like this:

# Generic settings
Host *
    ServerAliveInterval 600
    ControlPath /tmp/ssh-%r@%h:%p
    ControlMaster auto
    KeepAlive yes
    IdentityFile ~/.ssh/id_rsa.pub

Transaction looks like this when I login when I ssh into my box:

{12-12-03 9:41}hbrown-wks2:~/workspace/spt/project@master??? hbrown% git pull
Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': 
Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': 
Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': 
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Using bash does not appear to make a difference (i.e. ssh-agent /bin/bash).

This is a recent development, but I can't cite the change that caused it.
