Hi ISC,
there is problem with conflicting symbols. If dhcp server is configured
--with-ldap and --disable-static, it will use getaddrinfo from glibc
library.
However if bind library is linked dynamically using --with-libtool, it
will provide getaddrinfo symbol from irs library. If such bind library
is used in --with-libbind in dhcp, it breaks the server. It compiles fine.
However when started, recent openldap library will try to use
hint=AI_ADDRCONFIG in getaddrinfo. See [1] Because bind implementation
of lib/irs/getaddrinfo.c does no support such flag, it will always
return failure. Do I miss a way to link dhcp with ldap support, while
using only dynamic linking?
I have already reported it as suggestion #44024. Is there other
workaround than mentioned?
Best Regards,
Petr Menšík
