Hello all,
I'm trying to use RSE to connect to an AIX system which uses Kerberos, thru the DataStore daemon, but I always receive the message "Invalid password or user ID".
I've changed auth.pl replacing the traditional UNIX authentication for a call to a an external program which authenticates the username and password information against Kerberos and the PAM (Pluggable Authentication Module) architecture in AIX: (calling pam_authenticate(),....).
The original auth.pl file contained the following (relevant) lines:
$pwdIN = <STDIN>;
chomp($pwdIN);
@passwdStruct = getpwnam($userIN);
$passwd=$passwdStruct[1];
$encryptedPWD = crypt($pwdIN, $passwd);
if ($passwd eq $encryptedPWD)
{
system("su $suOptions $userIN -c '$javaExe -Duser.home=$homeDir -cp $classpath -DA_PLUGIN_PATH=$pathIN -DDSTORE_SPIRIT_ON=true org.eclipse.dstore.core.server.Server $portIN $timeoutIN $ticketIN'");
1;
}
And the modified one:
$pwdIN = <STDIN>;
chomp($pwdIN);
$result = system("authenticatePAM " . $userIN . " " . $pwdIN);
if ($result == 0)
{
system("su $suOptions $userIN -c '$javaExe -Duser.home=$homeDir -cp $classpath -DA_PLUGIN_PATH=$pathIN -DDSTORE_SPIRIT_ON=true org.eclipse.dstore.core.server.Server $portIN $timeoutIN $ticketIN'");
1;
}
The external program (authenticatePAM) validates the user credentials and when it returns, the variable "result" takes the value "0" and, consequently, the "su" command is executed (btw, "$portIN" is "0"), but in Eclipse I get the "Invalid password or user ID ()" message and the client doesn't connect. However I am able to connect to a running server (server.sh), instead of to the daemon (daemon.pl) (obviously configuring the connection accordingly in Eclipse).
I'm using Eclipse 4.2.2, RSE 3.5, AIX 6.1 TL8.
Any suggestions? Any way to trace the program execution?
Many thanks
Alfonso Corona
