Verified the bug on SSSD version: sssd-1.14.0-43.el7_3.14 Steps followed during verification: 1. Setup ldap with with 25000 users. 2. Setup client with enumeration = true in sssd.conf 3. Run user auth and lookup to verify whether sssd_be process is hanged or not. Automated these steps in the SSSD Performance test suite and also executed the regression round.
