So we want to have the following scenerio: User logs in using pam only. Use pam_tally2.so to count login attempts Lock account after 3 failed login attempts

Our current settings only do the following: You fail the login intentionally 3 times.
It prompts saying you've been locked out due to 3 failures. You put in the proper password and it says you've been denied using PAM authentication You put in the proper password again and it allows you in.

What version of Tectia do you have?

In the syslog, before those messages, do you see other authentication methods failing for this user? For instance, the user could have a number of public keys that are tried before going to pam authentication. Also, the server is offering GSSAPI (Kerberos) authentication - if you are not using GSSAPI/Kerberos, you could disable this method in the server configuration to avoid failed authentication attempts.

The client user could try to log in using just keyboard-interactive method. Details depend on client version, but with Tectia 6.x you could try the command line option "sshg3 -oAllowedauthentications=keyboard-interactive user@server"
