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 Thorsten Scherf 2017-06-01 12:39:33 UTC 
Description of problem:

When ipa-backup is called for the first time, the LDAP database is exported to /var/lib/dirsrv/slapd-<instance>/ldif/<instance>-userRoot.ldif. db2ldif is called for this. The tool runs under the dirsrv user context. When you call ipa-restore, the same ldif file is mangled by RemoveRUVParser(). Since the tool runs under root, also the mangled ldif file is now owned by root. 

When you now call ipa-backup the next time, the db2ldif fails, because the tool does not have permissions to write to the ldif file which is owned by root (instead of dirsrv).


I think this is the problematic code in ldif2db():

  ipautil.backup_file(ldiffile)                                              
        with open(ldiffile, 'wb') as out_file:                                     
            ldif_writer = ldif.LDIFWriter(out_file)                                
            with open(srcldiffile, 'rb') as in_file:                               
                ldif_parser = RemoveRUVParser(in_file, ldif_writer, self.log)   
                ldif_parser.parse()           

Another problem is, that ipa-backup returns with "The ipa-backup command was successful" although the db2ldif failed.
