Why krb5kdc and kadmind sets up ports for listening differently ?

[Sachin Punadikar]

Hello,

While doing code walkthrough of krb5kdc and kadmind programs,
I noticed a difference between these two in the way it sets up the
ports for listening.
krb5kdc uses ioctl calls to get the interfaces list and then on each
interface/ip-address its sets up the port for listening.
While in case of kadmind it uses wildcard to set up the port for listening.

Any specific reason for having different approaches while setting up ports?

Thanks in advance !!!
