kpasswd not working

[GOMBAS Gabor <gombasg@inf.elte.hu>]

Hello,

I cannot make kpasswd to work. It gives the following error message:
kpasswd: krb5_change_password: Unknown error 4294967288

The failing function is the getaddrinfo call at the end of
roken_getaddrinfo_hostspec which returns a value of -8 (EAI_SERVICE). 
Heimdal is using the getaddrinfo function from glibc (version 2.1.3), not
the one supplied with libroken. The hostname and port parameters are
OK, the hints structure is zeroed out when calling getaddrinfo (passing a 
NULL as the hints parameter makes no difference). Any ideas what is wrong
here?
