Dear pam-list members. We(3 developers) have plan to develop additional functionalities about 'acount'. Please read and comment about it. - account expire date : disable account after some days. - account inactive date : disable account if account is not used for some days. - account suspend/resume date : disable account until suspend date and resume it after resume date. We want to add above 3 functionalities on pam_time modules. How about your thought? - max login : limit maximum logins. - max session : limit maximum sessions. These are made in new modules. - user can surrogate(su) superuser with his/her own password. I'll modify pam_wheel to support this optional functionality. And, We wil develop management tools via Web. Using this tool, user can configure pam using Web-browser. How about these plans? Also, We have plan to port pam modules(include existing pam modules) to solaris, hp-ux, aix. Can anyone tell me which OS(except above 3 OS and linux) support pam.? welcome any comment. Thanks for reading. --Junyoung Heo.
