Overall I think there need to be some better examples used here with KRB5_TRACE to actually show a user how it works. Generally clarity of how to use the variable needs to be improved too. Did you actually configure and test this?

Troubleshooting kerberos is complex, because kerberos is a dumpster fire of a service.
I don't think we shuold say this, and this line adds no value to the documentation.

Execute the action that triggers the &krb; authentication issue for example, logging into a service. |

Where are the examples? How the KRB5_TRACE help? How does it work? These are things that a user will want to know.
Show an example like:
KRB5_TRACE=/dev/stderr kinit username@realm

Enable <envar>KRB5_TRACE</envar> logging by setting the environment variable to a file where you want the | ||
trace logs to be saved. This file will contain detailed information on all the &krb; operations. |

instead of "krb operations" which doesn't make sense, try "kerberos commands that are executed".
During &krb; authentication, clients that run local processes using the <literal>system</literal> | ||
account, assign these processes to the machine account when accessing remote resources. The machine account | ||
is associated to the computer name registered with the domain controller and is distinct with a <literal>$</literal> | ||
sign.</para></note> |

This paragraph is very vague and potentially inaccurate. Machine accounts are no different to a user account. They just are representing that that entity is a machine, instead of a human. There isn't some magic that gives a "service" on the machine credentials either, it's done through keytabs that have extracted principal information.
I'm really not sure what you are trying to communicate in this note.

krb principals don't have permissions, what does this mean? KRB is authentication, not authorisation.

Ensure there is a proper DNS resolution for the KDC and other &krb; related services. |

grammar, this reads really awkwardly.
@Firstyear , its a little complex, would you be willing to give a demo? Meanwhile I will try what you have suggested in the mail.. |
