[Samba] About MIT kerberos

[L.P.H. van Belle]

If you really want that build. 

You need the krb5 from debian experimental, add the debian experimental sources.
apt-get build-dep krb5
dd krb5-1.19
dch --bpo
Save.
debuild -uc -us
And it rebuild krb5 for bullseye. 

Then hope, it finishes without errors. 

Setup a file/local repo, so you can add the build depends in it. 

Add my repo for bullseye deb and deb-src, get these samba 4.15.3 sources 
apt update && apt-get source samba && apt-get build-dep samba
cd samba-4.15.3
dch -v2:4.15.3-0.1expMIT1 --distribution=bullseye "Test build with MIT support"
cd ..debian 
editor rules

Now edit the line with the build options to you needs. 
Save it, cd .. 
and run 

debuild -b -uc -us

That should give you a good chance it will build.
