Red Hat Bugzilla – Bug 110024
des-cbc-crc:v4 in supported_enctypes breaks java compatibility
Last modified: 2007-04-18 12:59:28 EDT
Description of problem: this could easily be a java (jaas) bug, but I figured I'd begin by documenting my findings here, and let you guys check it out. if the des-cbc-crc:v4 is listed before des-cbc-crc:normal, which is the default, then you cannot succesfully authenticate using java JAAS (sun JDK 1.4.1 and 1.4.2 tested). removing des-cbc-crc:v4 AND RECREATING ENTIRE DATABASE (krb5_util create -s) solves problem. bug manifests as persistent: 'Integrity check on decrypted field failed (31)' error. Version-Release number of selected component (if applicable): redhat 8.0 and 9.0 are known affected. How reproducible: always Steps to Reproduce: 1.use default krb5 server. configure. create database. start 2.using sun jdk 1.4.2, run simple programs found in tutorial found at http://java.sun.com/j2se/1.4.2/docs/guide/security/jgss/tutorials/AcnOnly.html 3.run program, it will always fail with above error. Actual results: error message pasted above Expected results: successful authentication Additional info:
