Can't start isc-dhcpd-4.2.0 (PATCH)

Hans Liss Hans at Liss.pp.se

The algorithm's domain must have been miscopied from that page, then.

I found the reason for the unclear error message. omapi_auth_key_enter() 
in omapip/auth.c calls dst_key_free() to free an uninitialized pointer 
when the algorithm is unknown, which triggers the REQUIRE().

Patch included, with a more informative error message added.

Best regards,

Hans
