TeamCity Git VCS SSH connection with Custom Private Key throws JschException: Auth fail

Question

I can't seem to get TeamCity to read my Git (Gitolite) repository... I get an exception:

List remote refs failed: com.jcraft.jsch.JSchException: Auth fail

What I've tried: (I use PuTTY to export them to OpenSSH format)

1. Use personal working(!!) private/public keys
2. Generate private/public key with PuTTy for teamcity user
3. Generate private/public key from Git Bash with ssh-keygen for teamcity user

All private keys have passphrase and I use the Custom Private Key setting to configure it. My fetch url looks like this: git:ssh://user@host/path/to/repository

No matter what I try... I always get the same exception:

I do get other exceptions when the wrong path or passphrase are defined

SourceTree, git-cola, PuTTY, etc. are working fine...

I'm accustomed to use TeamCity with Stash/BitBucket and a username/password, which always seemed to work, but Gitolite won't let me use a username/password. :(

Answer 1

I had the same problem when trying use my Unfuddle git as a VCS Root. To actually fix it, I found the link here which specified changing the Username in the VCS Root Authentication Settings to git.
