The Qpopper PAM code changed a bit between 4.0.5, which works for you, and 4.0.11, which doesn't. For example, the calls on pam_acct_mgmt() and pam_set_cred() are in different orders. I'm not a PAM expert, nor one on HPUX. I'd like to get this resolved soon. Maybe someone on this list can help? I'm attaching a pop_pass.c file to replace the one in your 4.0.11 popper/ directory. It has slightly better diagnostics for tracing the pam calls. Can you please try it and send me the Qpopper trace?
