Symptom & Impact

User logins hang or time out when secldapclntd cannot reach LDAP.

Environment & Reproduction

Common after a network blip or LDAP server certificate rotation.

Root Cause Analysis

Cached binds expire and the client cannot establish a new TLS session.

Quick Triage

Run lsuser -R LDAP ALL to check resolution latency and timeouts.

Step-by-Step Diagnosis

Inspect /var/ldap/secldapclntd.log and ls-secldapclntd status.

Solution – Primary Fix

Restart with stop-secldapclntd && start-secldapclntd after fixing certs.

Solution – Alternative Approaches

Alternative: mksecldap -c -h host -a binddn -p pwd to re-enroll.

Verification & Acceptance Criteria

Verify with id user and lsuser user that authdomain=LDAP works.

Rollback Plan

Roll back to /etc/security/ldap/ldap.cfg backup if config breaks.

Prevention & Hardening

Tune heartbeatinterval and searchtimeout in ldap.cfg for resilience.
