Hi,
I have built qpopper(4.0.9) on hpux 11.11 using --with-pam option.
But when I try to test this I am getting the following o/p.
# telnet localhost 110
Trying...
Connected to localhost.
Escape character is '^]'.
+OK Qpopper (version 4.0.9) at skoda.ind.hp.com starting.
user test
+OK Password required for test.
pass test
Connection closed by foreign host.
when I debugged with gdb backtrace looks like this
#0 0x1bf50 in PAM_qpopper_conv (num_msg=3, msg=0x7f7f6598, resp=0x7f7f6520,

the msg structure(second argument for PAM_qpopper_conv) is generated within
__pam_input_output with num_msg=3 .msg[1] is showing bad address
(gdb) p (char *) msg[0]->msg
$26 = 0x7f7f2498 "Removing root credentials would break the rpc services that"
(gdb) p (char *) msg[1]->msg
Error accessing memory address 0x4: Bad address.
In libpam library,msg structure is created properly but PAM_qpopper_conv is
unable to access the msg memory structure
When I gave wrong password I am getting this error
# telnet localhost 110
Trying...
Connected to localhost.
Escape character is '^]'.
+OK Qpopper (version 4.0.9) at skoda.ind.hp.com starting.
user test
+OK Password required for test.
pass test1
-ERR [AUTH] PAM authentication failed for user "test": Authentication failed (9)
+OK Pop server at skoda.ind.hp.com signing off.
Connection closed by foreign host.
Seems it is authenticating but not able to read the msg structure
Hope you can help me to fix this issue or do I need to send any additional
information regard this issue.
Thanks & Regards,
Ravindranath
