[Pam-developers] Add option to ignore password expiration in pam_unix

Hello, OpenSSH sshd calls (correctly) pam_acct_mgmt even for authentication methods that do not involve user passwords. The attached patch allows pam_unix to optionally ignore the password expiration. What do you think about it? Would it be OK to commit if I provide also documentation of the no_pass_expiry option? -- Tomas Mraz No matter how far down the wrong road you've gone, turn back.
