PAM error - HPUX 11.23 IA64

[Faizulla]

Hello,

I have developed custom PAM module and my pam.conf looks like:
login auth sufficient pam_inhouse.so
login auth required libpam_hpsec.so.1
login auth required libpam_unix.so.1 try_first_pass
(I am using the same for account, session and password stacks)
Though the login is successful with the custom id(pam_inhouse returns success) it is still calling into libpam_hpsec and libpam_unix which will eventually return error and so the login is not successful. Setting "suufcient" control flag for all solves the problem. But as I can understand, that is not really a good solution. Is there any other thing that need to be considered when using libpam_hpsec?(extension provided by HPUX)

Thannks for your help,

To add more details-

The module pam_hpsec is stacked as andatory module above all the modules for making security checks before authentication.
I tried turnig off pam_hpsec like this.

# Authentication management
#
#login auth required libpam_hpsec.so.1
login auth sufficient pam_inhouse.so
login auth required libpam_unix.so.1 try_first_pass


I know this will not give me the additional security extensions provided by hp_sec but some level of isolation of the problem.

According to man pam_hpsec, you must use this module at the top of all the modules.

The use of pam_hpsec is mandatory for services like login, dtlogin, ftp, remsh/rexec and ssh. It is required that these services stack this module on the top of the stack above one or more non-optional modules such as pam_unix, pam_krb5, or pam_ldap. Application writers and system administrators must consider whether it is appropriate to use pam_hpsec for any given application.

Thanks for your reply. Yes, I have gone through the pam_hpsec manual page but I am unable to find out what is that thing making pam_hpsec to be loaded though I use "sufficient" for my inhouse module which I use at the top. When "sufficient" used and "inhouse" module returns true it should not call into pam_hpsec and pam_unix down the stack. I am just wondering if there are any specific settings to be done for pam_hpsec. Has anyone used any "inhouse" module with "pam_hpsec" successfully?

Thanks for your help,
