Oh dear, you don't know what those are, without them you have no user |
| 23 |
accounts and can't log in :-) |
| 24 |
|
| 25 |
shadow implements the Unix password scheme using /etc/shadow, plus all |
| 26 |
the helper commands like useradd|mod|del etc |
| 27 |
|
| 28 |
PAM is Pluggable Authentication Modules - a bunch of rules and configs |
| 29 |
where you determine what exactly comprises a successful authentication. |
| 30 |
If you wanted to implement a fingerprint swiper and retina scanner, |
| 31 |
easiest would to be fit all that plumbing into PAM and tell the system |
| 32 |
to use it. PAM ships out of the box using shadow as the default way to |
| 33 |
auth users (i.e. by password). |
| 34 |
|
| 35 |
pambase is what implements this default method. pam (the full thing) |
| 36 |
implements the plumbing you need for everything else. |
| 37 |
|
| 38 |
shadow and pam are renowned for causing blockers that can't be |
| 39 |
automagically resolved, it's because they slot in at very low levels. |

Indeed. I find the only thing worse is icu. Even though the only docs I |
| 48 |
have ever read are in English (usually the Queen's version), I still |
| 49 |
can't get that thing off the system - libreoffice insists |
