kadmin | Kerberos Administration Interface for Scala
kandi X-RAY | kadmin Summary
kandi X-RAY | kadmin Summary
A type-safe wrapper around the kadmin command for Scala. In the JVM there are no libraries to create or delete kerberos principals. This is due to the fact that Kerberos only offers a C API, and interfacing with it via the Java Native Interface (JNI) can be a hard task to accomplish properly. We solve the problem of Kerberos administration in JVM via the only other alternative: by launching the kadmin command and write to its standard input and read from its standard output. To simplify this process we use scala-expect.

to be image_file_w200_png
. What you are doing there currently is defining a new field rather than changing your existing field because the names are not the same.
You could also define it in a different way in your class Meta:
section. You can add a dictionary called widgets

I am trying to implement n-retry topic with DLT but all the messages are being pushed to a single topic test-topic-retry-0, there are 3 duplicate records in test-topic-retry-0 which are supposed to be like this:
- test-topic-retry-0 -> 1 message after failure
- test-topic-retry-1 -> 1 message after the first retry
- test-topic-dlt -> 1 message after all the retries failed
It seems like Kafka is pushing all the messages to same topic.

QUESTION
I have installed a FreeIPA master server including Kerberos. Furthermore I have one client server, enrolled in FreeIPA, to test the PKINIT feature of Kerberos. All servers run on CentOS7.
A testuser exists in FreeIPA and this user is also listed in the one and only existing realm, when using list_principals
in kadmin
as testuser@REALMNAME.
getprinc testuser
also gives Attributes: REQUIRES_PRE_AUTH
.
I have created kdc and client certificates strictly following the documentation: https://web.mit.edu/kerberos/www/krb5-latest/doc/admin/pkinit.html. They have been signed by my own CA, whose certificate is also present on the client and the master.
The [realm] config on the master is as follows:
