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 of problem:
ds-replcheck command returns traceback errors against ldif files having garbage content when run in offline mode

Version-Release number of selected component (if applicable):
389-ds-base-1.3.8.4-3.el7.x86_64


How reproducible:
Always

Steps to Reproduce:
# ds-replcheck -v -M a.ldif -R b.ldif
Performing offline report...
Gathering all the DN's...
Gathering the database RUV's...
Traceback (most recent call last):
  File "/usr/bin/ds-replcheck", line 1290, in <module>
    main()
  File "/usr/bin/ds-replcheck", line 1279, in main
    do_offline_report(opts, OUTPUT_FILE)
  File "/usr/bin/ds-replcheck", line 575, in do_offline_report
    opts['master_ruv'] = get_ldif_ruv(MLDIF, opts)
  File "/usr/bin/ds-replcheck", line 417, in get_ldif_ruv
    result = ldif_search(LDIF, opts['ruv_dn'])
KeyError: 'ruv_dn'

I am getting traceback if I have garbage content in ldif files.

# cat a.ldif 
dsfcdfdfdef
dsfcdfdsfsfds

Actual results:
the command crashes

Expected results:
The command should not report any trackback errors and report that the files have invalid content or some proper error message.
