### Apache Airflow version 2.3.4 ### What happened Hi, In my infrastructure, we are using Kerberos Heimdal for our keytabs. I can see that airflow seems to be using MIT... I managed to switch to Heimdal by customizing the image : replacing krb5 packages with heimdal-clients. ``` ADDITIONAL_RUNTIME_APT_DEPS="" RUNTIME_APT_DEPS="apt-transport-https apt-utils ca-certificates curl dumb-init freetds-bin gosu heimdal-clients ldap-utils libffi7 libldap-2.4-2 libsasl2-2 libsasl2-modules libssl1.1 locales lsb-release netcat openssh-client python3-selinux rsync sasl2-bin sqlite3 sudo unixodbc" ``` But the kinit command used by Airflow seems to be specific with MIT : ``` airflow@7e253512ada7:/opt/airflow$ kinit -f -a -r 5m -k -t /opt/airflow/security/airflow.service.keytab -c /tmp/airflow_krb5_ccache airflow/dtl-airflowdocker01-d01.dc05@DC05 5m@DC05's Password: kinit: krb5_get_init_creds: Client (5m@DC05) unknown ``` the "-r 5m" seems to be the problem. Adding --renewable or deleting -r 5m seems to fix this issue. But how to "fix" this properly ? Regards, ### What you think should happen instead Either : - find a way to switch to Heimdal properly - maybe an option to customize args to kinit - ... ### How to reproduce Use kerberos with Heimdal. ### Operating System Debian (Docker) ### Versions of Apache Airflow Providers ``` airflow-exporter==1.5.3 apache-airflow==2.3.4 apache-airflow-providers-amazon==5.0.0 apache-airflow-providers-apache-cassandra==3.0.0 apache-airflow-providers-apache-hdfs==3.1.0 apache-airflow-providers-celery==3.0.0 apache-airflow-providers-cncf-kubernetes==4.3.0 apache-airflow-providers-common-sql==1.1.0 apache-airflow-providers-docker==3.1.0 apache-airflow-providers-elasticsearch==4.2.0 apache-airflow-providers-ftp==3.1.0 apache-airflow-providers-google==8.3.0 apache-airflow-providers-grpc==3.0.0 apache-airflow-providers-hashicorp==3.1.0 apache-airflow-providers-http==4.0.0 apache-airflow-providers-imap==3.0.0 apache-airflow-providers-microsoft-azure==4.2.0 apache-airflow-providers-mysql==3.2.0 apache-airflow-providers-odbc==3.1.1 apache-airflow-providers-postgres==5.2.0 apache-airflow-providers-redis==3.0.0 apache-airflow-providers-sendgrid==3.0.0 apache-airflow-providers-sftp==4.0.0 apache-airflow-providers-slack==5.1.0 apache-airflow-providers-sqlite==3.2.0 apache-airflow-providers-ssh==3.1.0 google-cloud-orchestration-airflow==1.4.1 ``` ### Deployment Other Docker-based deployment ### Deployment details _No response_ ### Anything else _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
