...which is residing in the sqlite3 database only (and not in /etc/passwd), the authentication failed. The problem I found was, when an ssh is attempted, OpenSSH module is trying to get the user info from the /etc/passwd file and when it found that the user does not exist, it passes "#010#012#015#177INCORRECT" as the password (and discards the password entered by the user) to the libpam_sqlite module. Then obviously the libpam_sqlite3 denies access to the user because the password is incorrect! When looked into the OpenSSH code, I found that getpwnam() in auth.c::getpwnamallow() sets pw = NULL and...

...est I'm usign PAM to direct the authentication request to the radius server. That part works fine. But the request coming to the radius looks like : User-Name = "test" User-Password = "\010\n\INCORRECT" I found this in : auth-pam.c badpw[] = "\b\n\r\177INCORRECT"; - What is supposed to be the behaviour of ssh when it is used with PAM ? Shall SSh pass on to PAM the exact credentials entered at the prompt (username and passwd) without affecting them (by putting "INCORRECT" in the passwd : buffer_put_cstring(&buffer, badpw); auth-pam.c in...

...t delay if the password was right). The call of pam requires a callback function via which the pam module is able to tell something. Things like information and errors BUT also to ask for further input. The callback function of sshd for the pam module returns allways the hard coded value \b\n\r\177INCORRECT in the case of using for further input as input from user, if is called in the a case mentioned in first paragraph. This behaviour is implemented to make sure that the timing on trying to login as the root user is handle same if it allowed by "PermitRootLogin" or not. It is NOT the code...
