Bug 29

ssh login using publickey authentication to an AIX system with NFS mounted 
home directory fails, prompts for password, and then succeeds when password is 
entered.  Fails using protocol 1 and 2.  Remote system is running OpenSSH 
3.0.2p1.  Failures occur when user's remte home directory and .ssh directory 
are set to 700.  If permissions on both directories are set to 711 or the NFS 
mounted home directory is exported with root access, the login succeeds 
without prompting for a password.  Problem existed in 2.9.9p2, but not in 
2.9p2. Verbose output of login follows.
