<user name>
Name of the remote user.
<error detail>
Describes the reason for the authentication failure.
Cause: An error occurred during the authentication of the user. Typical errors are:
"User not found": <user name> does not exist in the SSHCTL.
"User is frozen": <user name> exists in the SSHCTL but is frozen.
Effect: The remote SSH user cannot be authenticated. The session will be terminated.
Recovery: Any corrective action depends on the reason for the authentication failure. It may be required to
add, correct or thaw a user name using SSHCOM.
<session id>: No more authentication requests possible for <user name>
<user name>
Name of the remote user.
Cause: The maximum number of authentication requests exceeded. Typically, this condition can occur with
password authentication, if the SSH clients sends an invalid password for three times.
Effect: The remote SSH user cannot be authenticated. The session will be terminated.
Recovery: Use correct credentials for the user with the SSH client.
<session id>: password change for user <user name> failed: <error detail>
<user name>
Name of the remote user
<error detail>
is a description of the error that made the password change fail.
Cause: An error occurred when trying to change the user’s password, upon request of the SSH client.
Effect: The password could not be changed.
Recovery: Any corrective action depends on cause.
<session id>: public key authentication failed, algorithm not supported.
Cause: The SSH client tried to use an algorithm for public key authentication that is not supported by SSH2.
Effect: The password could not be changed
Recovery: Configure the SSH client to use a public key algorithm supported by SSH2.
<session id>: public key authentication failed, too many keys
Cause: The SSH client has more than ten public keys that did not match any public key stored for the user in
the SSHCTL.
Effect: The public key authentication is aborted. The user cannot be authenticated.
