Symptom & Impact

AIX LDAP clients see lag between master and replica directories.

Environment & Reproduction

Triggered by heavy lpps loads or replication agreement break.

Root Cause Analysis

ibmslapd replica falls behind, causing stale lsuser data.

Quick Triage

Run lsldap -h replica user vs lsldap -h master user to compare.

Step-by-Step Diagnosis

Check /var/ldap/ibmslapd.log for REPL_ERROR entries.

Solution – Primary Fix

Restart replication with idsldapdiff and ibmdirctl -D bind -w pwd start.

Solution – Alternative Approaches

Alternative: re-seed the replica with idsdbback / idsdbrest.

Verification & Acceptance Criteria

Verify with lsldap -h replica time lag against master within 60s.

Rollback Plan

Capture ibmdirctl status output before/after for change records.

Prevention & Hardening

Schedule idsdbmaint and replication health checks weekly.
