Description Rob Crittenden 2021-09-01 17:34:19 UTC

+++ This bug was initially created as a clone of Bug #2000261 +++

This bug is created as a clone of upstream ticket:
https://pagure.io/freeipa/issue/8965

[description of the issue]
The fix for #8044 in commit 9fe984fed7a7091bd1366be95fdfa2f56f777bb8 replaced the LDAP_NO_SUCH_OBJECT error code at two places where it was actually correct. As a result lookups for UIDs or GIDs will return the generic LDAP_OPERATIONS_ERROR to clients if the UID or GID is coming from a different domain than the requested. Since the given UID or GID does not exists in the domain LDAP_NO_SUCH_OBJECT is the right return code and would help the client to act accordingly.

#### Steps to Reproduce
1. Setup IPA with trust to AD
2. Set the domain resolution order so that the trusted AD domain is looked up first
3. On an IPA client call `getent passwd UID_of_an_IPA_user` or `getent group GID_Of-IPA_group`

#### Actual behavior
With `debug_level = 9` in the `sssd_nss.log` messages like `Data Provider Error: 3, 1432158230, Network I/O Error` and in the backend log messages like `ldap_extended_operation result: Operations error(1), Failed to handle the request.` can be seen.

#### Expected behavior
Nss responder and backend log should just indicate that the given UID or GID is not present in the given domain.

#### Version/Release/Distribution
ipa-4.6 and above, all versions where fox for #8044 was applied.
