RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Petr Vobornik 2016-07-13 12:04:27 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/6030

Hi,

The Directory Services crashes several times a day. It's installed on CentOS 7 VM :

Installed Packages
Name        : ipa-server
Arch        : x86_64
Version     : 4.2.0

# ipactl status

Directory Service: STOPPED

krb5kdc Service: RUNNING

kadmin Service: RUNNING

ipa_memcached Service: RUNNING

httpd Service: RUNNING

pki-tomcatd Service: RUNNING

ipa-otpd Service: RUNNING

ipa: INFO: The ipactl command was successful


Before each crash, I have these messages in /var/log/dirsrv/slapd-XXXXX/errors :

    [30/Jun/2016:09:35:19 +0100] ipapwd_encrypt_encode_key - [file encoding.c, line 171]: generating kerberos keys failed [Invalid argument]
    
    [30/Jun/2016:09:35:19 +0100] ipapwd_gen_hashes - [file encoding.c, line 225]: key encryption/encoding failed


There is a bug in ipapwd plugin which causes Directory Service crash when some users try to bind.

Please take a look to attached core file.

Best regards
