(7.4.z) WFLY-17768 - Incorrect allow_weak_crypto value in testsuite krb5.conf file

XMLWordPrintable

      Since Oracle Java SE 8u351, we start to see test failures from AdvancedLdapLoginModuleTestCase and SPNEGOLoginModuleTestCase (both testes were removed in upstream WFLY) in one of our downstream CI machine. i.e.

      The cause is Deprecate 3DES and RC4 in Kerberos (JDK-8139348). The RN mentions that "Users can set allow_weak_crypto = true in the krb5.conf configuration file  to re-enable" This is actually what we have already configured in https://github.com/wildfly/wildfly/blob/27.0.1.Final/testsuite/shared/src/main/resources/org/jboss/as/test/integration/security/common/krb5.conf#LL8 for our testsuite. But the value is incorrect, it should be allow_weak_crypto = true instead.

      The allow_weak_crypto attribuet is described here https://web.mit.edu/kerberos/krb5-1.12/doc/admin/conf_files/krb5_conf.html#libdefaults
