Hi,
While reviewing the installation of Kallithea on a test server, one of our 
college Unix admins pointed out two issues with the way SSH public keys are 
saved in .ssh/authorized_keys

1) When a user is deleted from the Kallithea system, the public key is not 
removed from the file. The only thing stopping access through SSH is when 
Kallithea does not find an active user and denies the request. It seems to me 
that removing the public key would greatly reduce the processing done before 
access is refused.

2) When a user submits a public key through the Web interface, the comment at 
the end of the key line is not copied into the authorized_keys file. The 
comment should be retained to help manually manage the file, or at least 
identify the users at a glance. Yes, I agree that the file is managed by the 
system, but sometimes you need to look at it.

If you'd like, I can enter the issue in bitbucket, but at the moment it seems 
to be undergoing maintenance.

Thanks
