Passwordless authentication via SSH
I am trying to implement passwordless authentication via ssh2. I have used the well documented technique of generating a key pair with a blank passphrase on my client machine, and installing the public key on the destination server (AIX 5.3) in the user's .ssh2 directory. I have used this technique successfully in the past on other flavours of Unix.
However when I connect (e.g. using sftp2) it still asks for a password, and I have to supply the user's Unix account password before it lets me in. What have I missed? Is there a setting somewhere else that is overriding those in the sshd2 config file?

condor_store_cred
condor_store_cred(1) General Commands Manual condor_store_cred(1)
Name
condor_store_cred securely - stash a password
Synopsis
condor_store_cred [-help]
condor_store_credadd[ -c | -u username] [-p password] [-n machinename] [-f filename]
condor_store_creddelete[ -c | -u username] [-n machinename]
condor_store_credquery[ -c | -u username] [-n machinename]
Description
condor_store_credstores passwords in a secure manner. There are two separate uses of condor_store_cred:
1. A shared pool password is needed in order to implement the PASSWORD authentication method. condor_store_cred using the -coption
deals with the password for the implied condor_pool@$(UID_DOMAIN) user name.
On a Unix machine, condor_store_cred with the -foption is used to set the pool password, as needed when used with the PASSWORD authen-
tication method. The pool password is placed in a file specified by the SEC_PASSWORD_FILE configuration variable.
2. In order to submit a job from a Windows platform machine, or to execute a job on a Windows platform machine utilizing the run_as_own-
erfunctionality, condor_store_cred stores the password of a user/domain pair securely in the Windows registry. Using this stored pass-
word, Condor may act on behalf of the submitting user to access files, such as writing output or log files. Condor is able to run jobs
with the user ID of the submitting user. The password is stored in the same manner as the system does when setting or changing account
passwords.
Passwords are stashed in a persistent manner; they are maintained across system reboots.
The addargument on the Windows platform stores the password securely in the registry. The user is prompted to enter the password twice for
confirmation, and characters are not echoed. If there is already a password stashed, the old password will be overwritten by the new pass-
word.
The deleteargument deletes the current password, if it exists.
The queryreports whether the password is stored or not.
Options
-c
Operations refer to the pool password, as used in the PASSWORD authentication method.
-f filename
For Unix machines only, generates a pool password file named filenamethat may be used with the PASSWORD authentication method.
-help
Displays a brief summary of command options.
-n machinename
Apply the command on the given machine.
-p password
Stores password, rather than prompting the user to enter a password.
-u username
Specify the user name.
Exit Status
condor_store_credwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
