An administrator is monitoring an OpenLDAP server and sees that the 'threads' counter in slapd-metrics is high, but the CPU is only at 20%. The server is rejecting new connections. What is the most likely cause?

The connection limit is reached, and the threads are idle waiting for work.

The cache is too small, causing threads to be busy.

The loglevel is too high, causing threads to be busy.

The threads are blocked on I/O, and the thread pool is exhausted.

An administrator is troubleshooting slow searches on an OpenLDAP server. The searches are for users in a specific organizational unit, using the filter (ou=engineering). The administrator suspects the index is not being used. Which command will help confirm this?

ldapsearch -d 1 -b dc=example,dc=com '(ou=engineering)'

slapcat -d 1 -b dc=example,dc=com

slapindex -v -f /etc/ldap/slapd.conf

ldapsearch -x -LLL '(ou=engineering)'
