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.

Doc Type: Bug Fix
Doc Text:
Cause: IPA netgroup plugin does not validate netgroup names. Consequence: A netgroup with invalid name can be stored in LDAP server which may then crash when the invalid value is processed by NIS plugin. Fix: IPA netgroup plugin enforces stricter validation for netgroup names. Result: User cannot accidentally enter invalid netgroup and thus cause an LDAP server to crash because of NIS plugin processing.

Description Dmitri Pal 2012-01-05 18:13:24 UTC 
+++ This bug was initially created as a clone of Bug #770952 +++

Description of problem:

When you create an NIS netgroup named +(hostgroup), 389 crashes and then crashes on startup (last log item is a note about database recovery).

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

2.1.4-3.fc16.x86_64 (from updates-testing as of 2011-12-29)

How reproducible:

Haven't tried on a test setup, consistently crashed, however.

Steps to Reproduce:
1. Create a hostgroup "buildserv"
2. Add a server to it
3. Create a sudo command-group "software-install" that mirrors the standard SOFTWARE cmnd_alias.
4. Create a sudo rule "developers_buildserv" which allows members of the "developers" group to run softare on the host named "+buildserv"
5. Create an NIS netgroup "+buildserv"

Actual results:

389 crashes, crashes again when restarting.

Expected results:

The server refuses to create +buildserv, lets you know you're doing something dumb.

Additional info:

The corrective action was:

1. Use db2ldif to dump the database to LDIF
2. Manually edit the dump to rename the "buildserv" netgroup
3. Re-import with ldif2db
4. Delete the host group
5. Delete the netgroup
6. Re-add the host group.

Allowed characters are a-z, 0-9, -, _ and .

Also restricting hostgroup names with same list.
