Hi folks,
I'm trying to use PAM auth on PostgreSQL, but I still cannot
get success on PAM auth (with PG813 and RHEL3).
pg_hba.conf has
> host pamtest all 0.0.0.0/0 pam
/etc/pam.d/postgresql is
> #%PAM-1.0
> auth required pam_stack.so service=system-auth
> account required pam_stack.so service=system-auth
> password required pam_stack.so service=system-auth
And I've changed user password with "ALTER USER ... PASSWORD".
However, my postmaster always denies my login.
---------------------------------------------------------
% /usr/local/pgsql813/bin/psql -h localhost -W -U hoge pamtest
Password for user hoge:
LOG: pam_authenticate failed: Authentication failure
FATAL: PAM authentication failed for user "hoge"
psql: FATAL: PAM authentication failed for user "hoge"
---------------------------------------------------------
What's wrong with that?
BTW, I found an empty password ("") is passed to CheckPAMAuth()
function in auth.c.
---------------------------------------------------------
#ifdef USE_PAM case uaPAM: pam_port_cludge = port; status = CheckPAMAuth(port,
port->user_name,""); break;
#endif /* USE_PAM */
---------------------------------------------------------
/** Check authentication against PAM.*/
static int
CheckPAMAuth(Port *port, char *user, char *password)
{ int retval; pam_handle_t *pamh = NULL;
/* * Apparently, Solaris 2.6 is broken, and needs ugly static variable * workaround */ pam_passwd =
password;
/* * Set the application data portion of the conversation struct This is * later used inside the PAM
conversationto pass the password to the * authentication module. */ pam_passw_conv.appdata_ptr = (char *)
password; /* from password above, * not allocated */
---------------------------------------------------------
What does it mean? I'm not familiar with PAM, so I can't get
why the password can be empty here.
Any suggestion?
Thanks.
