Subject: configure.ac: remove redundant check for pam_fail_delay
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ee8385d78197b5e60fc80a3519bc67b42795e903;p=thirdparty%2Fshadow.git

configure.ac: remove redundant check for pam_fail_delay

This check was introduced in 276e406c (support for OpenPAM).
OpenPAM has never declared pam_fail_delay.

linux-pam has defined HAVE_PAM_FAIL_DELAY in its headers for a very long
time (before version history).
