System-provided Heimdal Kerberos in FreeBSD 9 lacks proper support for parsing MS PAC. This leaves us with MIT krb5 package from ports or embedded Heimdal in source4. MIT krb5 from ports is 1.9.2, it supports all needed features for AD support in smbd, as well as WAF MIT krb5 build. In order to use it, one needs to install 'krb5' package. Autoconf build: --with-krb5=/usr/local WAF build: --with-system-mitkrb5 /usr/local or otherwise krb5-config from system Heimdal will overtake and break the detection, leaving you with a mixture of Kerberos libraries from different locations. WAF build accepts multiple paths as sub-arguments of the --with-system-mitkrb5 and searches through them for krb5-config, i.e. /usr/local /usr/kerberos ...
