pam_stack(8) |

pam_stack − recurse into other PAM stacks
auth
required /lib/security/pam_stack.so service=foo
session optional /lib/security/pam_stack.so service=foo
password optional /lib/security/pam_stack.so service=foo
account optional /lib/security/pam_stack.so
service=foo
In a nutshell, pam_stack lets you "call", from inside of the stack for a particular service, the stack defined for any another service. The intention is to allow multiple services to "include" a system-wide setup, so that when that setup needs to be changed, it need only be changed in one place.

turns on debugging via syslog(3). |
service=name
tells pam_stack.so to execute the stack defined for the service name, which will usually be another file in /etc/pam.d.
/etc/pam.d/imap:
auth required /lib/security/pam_stack.so service=system-auth
auth required /lib/security/pam_shells.so
/etc/pam.d/system-auth:
auth sufficient /lib/security/pam_krb5.so
auth sufficient /lib/security/pam_unix.so shadow nullok
auth required /lib/security/pam_deny.so
Because recursion is fully supported, there is potential to really break things by having a stack call itself either directly or via mutual recursion.
Let’s hope not, but if you find any, please email the author.
