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 Luc de Louw 2015-11-03 15:02:19 UTC
Description of problem:

when creating an ID view in IPA and override one or more users credentials such as UID, GID, Shell etc.


Version-Release number of selected component (if applicable):
slapi-nis-0.54-3.el7_1.x86_64


How reproducible:
Always


Steps to Reproduce:
1. Install IPA
2. Add a user: ipa user-add --first=Joe --last=Doe --shell=/bin/bash jdoe
3. Add idview: ipa idview-add legacy-servers --desc "Our legacy servers"
4. Map user: ipa idoverrideuser-add --uid=1001 --shell=/bin/ksh legacy-servers jdoe
5. Configure client to use the ID view via LDAP
authconfig --updateall --enableldap --enableldapauth --ldapserver=ldap://ipa3.example.com --ldapbasedn=cn=users,cn=legacy-servers,cn=views,cn=compat,dc=example,dc=com
6. getent passwd jdoe returns
uid=936200001(jdoe) gid=936200001 groups=936200001
7. Issue an ldapsearch:
ldapsearch -LLL -x -b cn=users,cn=legacy-servers,cn=views,cn=compat,dc=example,dc=com -D "cn=Directory Manager" -W uid=jdoe
Enter LDAP Password: 
dn: uid=jdoe,cn=users,cn=legacy-servers,cn=views,cn=compat,dc=example,dc=com
cn: Joe Doe
objectClass: posixAccount
objectClass: top
gidNumber: 936200001
gecos: Joe Doe
uidNumber: 936200001
uidNumber: 1001
loginShell: /bin/bash
loginShell: /bin/ksh
homeDirectory: /home/jdoe
uid: jdoe


Actual results:
The mapped attributes are not a unique answer but duplicated with the original entries.


Expected results:
getent passwd and others should return only the mapped attributes


Additional info:
With sssd it works as expected, but LDAP access to ID views are critical for Linux Systems with no SSSD and Legacy Unix Systems such as AIX, Solaris and others.g
