Description of problem: AD authentication appears not to work. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Join Fedora 33 to Windows Domain 2. Try to login as an AD user 3. Actual results: 1. Had to add the following to the krb5.conf file to allow it to join the domain: default_tgs_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 default_tkt_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 permitted_enctypes = rc4-hmac des-cbc-crc des-cbc-md5 allow_weak_crypto = true After than able to join successfully. [root@F33-JK log]# realm list xxx.ie type: kerberos realm-name: XXX.IE domain-name: xxx.ie configured: kerberos-member server-software: active-directory client-software: sssd required-package: oddjob required-package: oddjob-mkhomedir required-package: sssd required-package: adcli required-package: samba-common-tools login-formats: %U login-policy: allow-realm-logins 2. Trying to log in results in invalid user & lots of these messages in the journal: Nov 30 10:58:14 F33-JK.xxx.ie ldap_child[2662][2662]: Failed to initialize credentials using keytab [MEMORY:/etc/krb5.keytab]: Pre-authentication failed: Key table entry not found. Unable to create GSSAPI-encrypted LDAP connection. Expected results: Successful authentication. Additional info: I've this working successfully on Centos 7.9 although I did not have to add the extra encryption options to krb5.conf in that case.
Not related to openldap. Our guess is it impacts SSSD (just a guess)
Please enable debug logs for the domain section of sssd.conf and provide at least that one and ldap_child.log.
Hi, additionally it would be good if you can send the output of 'klist -kte' as well. bye, Sumit
