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 Scott Poore 2012-12-13 20:21:39 UTC 
Description of problem:

ipa netgroup-mod (and maybe others) commands for setattr with empty value returns an internal server error like this:

[root@rhel6-1 ~]# ipa netgroup-add testng1 --desc=desc
------------------------
Added netgroup "testng1"
------------------------
  Netgroup name: testng1
  Description: desc
  NIS domain name: testrelm.com
  IPA unique ID: 3661ef20-418d-11e2-9258-525400640001


[root@rhel6-1 ~]# ipa netgroup-mod --setattr=memberuser="" testng1
ipa: ERROR: an internal error has occurred

[root@rhel6-1 httpd]# ipa netgroup-mod --setattr=memberhost="" testng1
ipa: ERROR: an internal error has occurred

And maybe others?

Version-Release number of selected component (if applicable):

ipa-server-3.0.0-10.el6.x86_64

How reproducible:

Always

Steps to Reproduce:
1. Setup IPA Server
2. ipa netgroup-add testng1 --desc="test netgroup"
3. ipa netgroup-add-member testng1 --users=admin
4. ipa netgroup-mod testng1 --setattr=memberuser=""
5. ipa netgroup-mod testng1 --setattr=memberhost=""
  
Actual results:

Internal Server Errors

Expected results:

Normal error message.

For #4, I'd also expected the users for testng1 to be deleted so they're now empty.
