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

Fix is seen.
Verified on RHEL7.3 using the below rpm.
