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 Kaushik Banerjee 2011-05-25 09:57:00 UTC 
Description of problem:
Unable to authenticate users when username contains "\0"

Version-Release number of selected component (if applicable):
sssd-1.5.1-34.el6.i686

How reproducible:
Always

Steps to Reproduce:
1. Create a user in DS using the following ldif
dn: uid=usr\\007,ou=People,dc=example,dc=com
uidNumber: 90099
gidNumber: 90099
objectClass: top
objectClass: posixAccount
objectClass: person
cn: usr\\007
homeDirectory: /export/usr007
userPassword: Secret123
sn: usr007

2.ldapsearch shows:
# usr\5C007, People, example.com
dn: uid=usr\5C007,ou=People,dc=example,dc=com
uidNumber: 90099
gidNumber: 90099
objectClass: top
objectClass: posixAccount
objectClass: person
cn: usr\\007
homeDirectory: /export/usr007
sn: usr007
uid: usr\007

3. Enumeration of user\\007:
# getent -s sss passwd usr\\007 
usr\007:*:90099:90099:usr\\007:/export/usr007:

4. Auth using user\\007:
# ssh -l usr\\007 localhost
usr\007@localhost's password: 
Permission denied, please try again.
usr\007@localhost's password: 

5. /var/log/secure shows:
May 25 15:19:22 rh61-x86 sshd[17978]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=localhost  user=usr\007
May 25 15:19:22 rh61-x86 sshd[17978]: pam_sss(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=localhost user=usr\007
May 25 15:19:22 rh61-x86 sshd[17978]: pam_sss(sshd:auth): received for user usr\007: 10 (User not known to the underlying authentication module)

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.
    
    New Contents:
Cause: SSSD did not correctly escape some special characters in user names
Consequence: initgroups and by extension login failed for users whose user name contained special characters
Fix: SSSD now uses a sanitize function to escape user names
Result: users with special characters in user names are able to log in now
