Fixed a crash with sudo ALL rules in the LDAP and SSSD back-ends. This is a regression introduced in sudo 1.9.8. Bug #994.
Fixed a compilation error when the --enable-static-sudoers configure option was specified. This is a regression introduced in sudo 1.9.8 caused by a symbol clash with the intercept and log server protobuf functions.
