My customer need add password policy to SLES…I reference these document
it seem only apply password that user change password by hiself.
and I check
it provide 2 point
(1)ÂThe complexity rules are not applicable to the password of the root user.
(2)ÂThe complexity rules are not applicable to the passwords configured by the root user for other users.
Whether these password by root indeed could apply password policy (I believe the third-party software could provide such function…but I just want to search official procedure now.)
