The helper is thus called only when SELinux is enabled on the system\&. +.PP +The interface of the helper \- command line options, and input/output data format are internal to the +\fIpam_pwhistory\fR +module and it should not be called directly from applications\&. +.SH "SEE ALSO" +.PP +\fBpam_pwhistory\fR(8) +.SH "AUTHOR" +.PP +Written by Tomas Mraz based on the code originally in +\fIpam_pwhistory and pam_unix\fR +modules\&. |
