Doc Text:
On 32-bit architectures, running the "getent passwd" command on a username with a very large user or group identifier (that is, UID or GID greater than 2147483647) resulted in an empty output. With this update, the underlying source code has been modified to address this issue, and the getent command now returns the expected output.

Description Gowrishankar Rajaiyan 2010-10-21 14:22:30 UTC 
Description of problem:
On 32bit platforms 'getent passwd <username>' returns nothing if its uidNumber > 2147483647.

Version-Release number of selected component (if applicable):
sssd-1.2.1-32.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Setup a LDAP server.
2. Add users and groups with very high uidNumber/gidNumber. ( gt 2147483647)
3. Configure sssd with id_provider = ldap.
4. getent passwd username
  
Actual results:
No results for <username>.

Expected results:
Users/groups with high uidNumber/gidNumber should be returned successfully.

Additional info:

1. This works fine on 64bit platforms.

2. This is reproducible on RHEL5.6 32bit platforms as well.

3. Relevant config section of sssd
[domain/LDAP]
id_provider = ldap
auth_provider = ldap
ldap_uri = ldaps://sssdldap.idm.lab.bos.redhat.com:636
ldap_search_base = dc=example,dc=com
cache_credentials = true
enumerate = true
debug_level = 9
ldap_tls_cacertdir = /etc/openldap/cacerts
ldap_tls_cacert = /etc/openldap/cacerts/cacert.asc
