[Freeipa-users] Trust between IPA and another MIT Kerberos Realm

[Matt Bryant]

Hmm just upgraded to 3 so thought I woudl give it a go ... but (aint 
there always one of those :() can't seem to add the principle ..

kadmin.local:  add_principal krbtgt/OLD-REALM at IPA-REALM
WARNING: no policy specified for krbtgt/OLD-REALM at IPA-REALM; defaulting 
to no policy
Enter password for principal "krbtgt/OLD-REALM at IPA-REALM":
Re-enter password for principal "krbtgt/OLD-REALM at IPA-REALM":
add_principal: Invalid argument while creating "krbtgt/OLD-REALM at IPA-REALM".

and nothing was placed in the kadmin log .. :(
