I’ve dealt with this exact scenario multiple times. The issue involves all four focus areas you need to address systematically:
1. LDAP Attribute Schema Validation
Your trainingRecord attribute exists, but verify the data type compatibility. Arena stores course completion as a complex object (course ID, completion date, score). LDAP expects a string or multi-value attribute. Add a transformation rule:
<attribute-map arena="courseCompleted" ldap="trainingRecord" direction="both">
<transform type="serialize" format="JSON"/>
<ldap-type>multiValue</ldap-type>
</attribute-map>
This serializes Arena’s course completion object into JSON strings that LDAP can store as multi-value attributes.
2. Service Account Permissions
Even with Modify permissions, check these specific requirements:
- Service account needs “Write trainingRecord” permission explicitly (not just generic Modify)
- Verify the account is NOT restricted by LDAP access control rules that limit writes to certain OUs
- In Active Directory, check that “Deny” permissions aren’t overriding your Allow permissions
- Test with ldapmodify command using the service account credentials:
ldapmodify -x -D "cn=arena_svc,ou=services,dc=company,dc=com" -W
dn: uid=testuser,ou=users,dc=company,dc=com
changetype: modify
replace: trainingRecord
trainingRecord: test-value
3. Sync Job Scheduling and Logging
Your hourly schedule is fine, but the logging configuration is critical for diagnosis:
- Admin > Integration > LDAP Connector > Advanced Settings
- Set `ldap.sync.log.level=DEBUG
- Enable
ldap.write.audit=true to track all write attempts
- Set
ldap.error.notification=true with your email
- Review logs at /logs/ldap-sync.log after next scheduled run
- Look specifically for “WRITE_FAILED” or “SCHEMA_VIOLATION” entries
4. Connector Authentication Settings
The connector might be using different credentials for read vs. write operations:
- Navigate to Admin > Integration > LDAP Connector > Authentication
- Verify both
read.connection.principal and write.connection.principal are set
- If write.connection.principal is not configured, it defaults to read-only mode
- Set explicitly:
<ldap-connector>
<authentication>
<read-principal>cn=arena_svc,ou=services,dc=company,dc=com</read-principal>
<write-principal>cn=arena_svc,ou=services,dc=company,dc=com</write-principal>
<credentials-store>encrypted</credentials-store>
</authentication>
</ldap-connector>
Complete Solution Steps:
- Update attribute mapping with explicit direction=“both” and data transformation
- Verify write-specific service account permissions with ldapmodify test
- Enable DEBUG logging and audit trail for sync operations
- Configure separate write.connection.principal in authentication settings
- Restart LDAP Connector service after configuration changes
- Manually trigger sync job and monitor logs for specific error messages
- Test with single user course completion before enabling for all users
The most common root cause is the missing write.connection.principal configuration combined with lack of data type transformation for complex Arena objects. After implementing these changes, your course completions should sync to LDAP within the next scheduled interval.
