Why teams connect Ldap and ServiceNow

Connect the tickets, records, and events in ServiceNow to the systems engineering runs in Ldap, kept current in real time and in both directions.

ServiceNow is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. Ldap is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.

Stacksync syncs Configuration Items (CMDB), Users and Groups, Tasks, Knowledge Articles in ServiceNow with Attributes, Operational attributes, Schema (subschema subentry), Entries in Ldap field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.

Common use cases

  • 01 Sync sys_user records with the HR system or identity provider so assignment groups stay accurate
  • 02 Mirror incident and task data into Postgres or a warehouse for SLA and workload reporting
  • 03 Incrementally sync changed entries by polling modifyTimestamp, keeping a downstream store fresh without dumping the whole directory each cycle.
  • 04 Keep group member and uniqueMember attributes aligned with application entitlement tables so directory access reflects the right teams as they change.

Common sync patterns

Where Ldap moves messages between services: activity lands on the stream

Records created or changed in ServiceNow publish to the queue or topic in Ldap as they happen, so downstream services react to real events rather than polling for them.

Where Ldap is the directory or identity source: one set of users

People and accounts in ServiceNow stay matched to the users in Ldap, so access, provisioning, and org changes propagate instead of being keyed in twice.

Where Ldap watches operations: live volumes for visibility

Open items, throughput, and error counts from ServiceNow replicate into Ldap, so the operational view reflects what is actually happening in the business.

What you can sync between Ldap and ServiceNow

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Ldap objects ServiceNow objects How this pairing syncs
Groups (groupOfNames / posixGroup) Group entries whose member or uniqueMember attributes list DNs; synced two-way to add and remove membership as teams and entitlements change. Problems Root-cause records linked to incidents, useful in cross-system reporting. Groups (groupOfNames / posixGroup) is specific to Ldap and Problems to ServiceNow — each maps to any object or custom field on the other side.
Organizational units (ou) Container entries that structure the DIT and scope which subtree a sync reads or writes; used to limit a sync to a branch such as ou=People,dc=corp,dc=com. Service Catalog Requests Requested items and approvals that often trigger provisioning in other systems. Organizational units (ou) is specific to Ldap and Service Catalog Requests to ServiceNow — each maps to any object or custom field on the other side.
Attributes The typed name/value pairs on each entry (cn, mail, memberOf, objectClass); the schema defines which attributes each objectClass allows, and mappings are built per attribute. Configuration Items (CMDB) Asset and infrastructure records synced with discovery tools and asset databases. Attributes is specific to Ldap and Configuration Items (CMDB) to ServiceNow — each maps to any object or custom field on the other side.
Operational attributes Server-maintained metadata such as modifyTimestamp, createTimestamp, entryUUID, entryCSN, and uSNChanged; read to drive incremental polling and to key entries stably across syncs. Users and Groups Sys_user and group tables synced with HR systems and identity providers. Operational attributes is specific to Ldap and Users and Groups to ServiceNow — each maps to any object or custom field on the other side.
Schema (subschema subentry) The objectClass and attribute-type definitions the server exposes; read to validate that written attributes exist and are single- or multi-valued as expected. Tasks The base task table that incidents, changes, and requests extend. Schema (subschema subentry) is specific to Ldap and Tasks to ServiceNow — each maps to any object or custom field on the other side.
Entries The fundamental unit of an LDAP directory, each addressed by a distinguished name (DN) and typed by its objectClass; synced two-way as records, with the DN driving upserts and attribute-level updates. Knowledge Articles Support content that can be mirrored to help centers or search indexes. Entries is specific to Ldap and Knowledge Articles to ServiceNow — each maps to any object or custom field on the other side.

How changes propagate between Ldap and ServiceNow

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Ldap ServiceNow Interval-based propagation

DetectionStacksync polls Ldap for changes on an incremental schedule, reading only records changed since the previous pass. No universal native change feed.

DeliveryEach detected change is written to ServiceNow through its API, with automatic retries and rate-limit backoff.

ServiceNow Ldap Interval-based propagation

DetectionStacksync polls ServiceNow for changes on an incremental schedule, reading only records changed since the previous pass. Polling on sys_updated_on timestamps.

DeliveryEach detected change is written to Ldap through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Ldap: LDAP defines no request quota; throughput is bounded by the server's sizelimit and timelimit administrative limits, connection and thread caps, and the CPU/IO it shares with live authentication traffic, so large syncs can contend with production lookups and must page results.
  • ServiceNow: Subject to instance-level API rate limits and concurrency semaphores configured by administrators.

How the Ldap and ServiceNow connectors work

Ldap

Integration surface
LDAPv3 protocol (RFC 4511) over TCP, typically LDAPS on port 636 or StartTLS on 389; reaches any LDAPv3 directory server - OpenLDAP, Microsoft Active Directory, 389 Directory Server, Oracle Unified Directory, PingDS/ForgeRock, NetIQ eDirectory, Apache Directory.
Authentication
A bind DN and password (simple bind), typically over TLS, using a service account with rights to the target subtree. SASL mechanisms - GSSAPI/Kerberos, DIGEST-MD5, or EXTERNAL with a client certificate - are available where the server supports them.
Change detection
No universal native change feed. Incremental sync polls the modifyTimestamp operational attribute (or entryCSN / uSNChanged on servers that expose them) for entries changed since the last cursor; detecting deletes needs a server changelog or tombstones because a plain search cannot see removed entries. Some servers add Persistent Search or RFC 4533 content-sync (syncrepl), but that support is server-specific. No webhooks.
