The Pluggabble Authentication Module controls minimum security requirements, such as password lengths.
|
||
|
|
||
|
Configuration rests in `/etc/pam.d/common-password`, or sometimes `system-auth`.
|
||
|
|
||
|
The file might be edited to contain:
|
||
|
|
||
|
```
|
||
|
|
||
|
password required pam_cracklib.so minlen=12 lcredit=1
|
||
|
|
||
|
ucredit=1 dcredit=2 ocredit=1
|
||
|
|
||
|
```
|
||
|
|
||
|
This would enforce a minimum length of 12 characters for a password, one lowercase character, one upper case character, two digits, and one other (special) character.
