Subject: Allow logger.c to work with redirected stderr
X-Git-Tag: krb5-1.13-beta1~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3aa3722bc9a07a5bc77cc09be0346226138ec2f7;p=thirdparty%2Fkrb5.git

Allow logger.c to work with redirected stderr

In lib/kadm5/logger.c:krb5_klog_init(), if the configuration requests
STDERR logging, call fdopen() using mode "w" instead of "a+", to avoid
errors when stderr happens to be opened for write only.

(cherry picked from commit a85923073ad2d1f5d0314ab330fd6c5f07749be8)
