Opened: Aug 10, 2022

Severity: 2-Critical

Symptoms

By default, our LDAP implementation was set to chase LDAP referrals. This could be expensive and make lookups very slow in large organizations with multiple layers of LDAP servers.

Impact

The default of chasing referrals in the above conditions could result in slow LDAP lookups and timeouts.

Conditions

LDAP enabled in very large LDAP organizations with multiple levels of servers.

Workaround

None

Fix Information

A chase referrals option was added to LDAP configuration. The default is still enabled, but now it can be easily disabled: system aaa authentication ldap chase-referrals false
