Description joel 2021-07-02 15:58:13 UTC

Description of problem:

Identity Management (IdM) ID Views under cn=compat broken starting with
slapi-nis-0.56.5-3.el7_9.x86_64. The only item in the changelog from the
previous (working) version, slapi-nis-0.56.5-2.el7.x86_64, was a fix for
BZ 1866113, which addressed a memory leak.


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

* slapi-nis-0.56.5-3.el7_9.x86_64
* slapi-nis-0.56.5-4.el7_9.x86_64
* Bug is still present in upstream, so RHEL 8 is probably also affected
  (https://pagure.io/slapi-nis/history/src/back-sch.c)


How reproducible:

Queries for any account or group under cn=views,cn=compat,dc=DOMAIN will
return LDAP error code 32 (NO_SUCH_OBJECT).


Steps to Reproduce:

1. Create any view, such as "myview". It doesn't even need to contain
   any attribute overrides.

2. Perform an LDAP query for any known user against cn=views,cn=compat
   using the named view you just created. (Assumes local query from an
   IdM replica using GSSAPI authentication and the local Unix socket.)

   ldapsearch -LLLQ -b 'cn=myview,cn=views,cn=compat,dc=DOMAIN' 'uid=admin' uid


Actual results:

result: 32 No such object
matchedDN: dc=DOMAIN


Expected results:

dn: uid=admin,cn=users,cn=compat,dc=DOMAIN
uid: admin


Additional info:

Queries against just cn=compat (not cn=views,cn=compat) are not affected.
Only queries meant to apply an ID View are affected.

Comment 3 Florence Blanc-Renaud 2021-07-06 14:41:55 UTC

The issue looks similar to BZ#1958909 for which a fix was recently found.

@tbordaz could you check if this is the same issue? Thanks

Comment 4 thierry bordaz 2021-07-06 15:51:13 UTC

Difficult to be sure without debugging but I think it is a different issue.
#1958909 was triggered by an incorrect test if the target base search is a subtree of IDview. This with the target base search being a child of IDview base and scope being 'base'

Here the base search is the IDview itself and the scope subtree, so it should work (IIUC).

An option to be sure is to test with idm-client-8050020210701113027.de73ecb2 that fixes 1958909.
