Issue/Introduction

After upgrading the Autamation engine, the following errors show up in the LDAP Sync log:

2022-11-15 20:26:14.079 [main] c.a.s.a.b.i.BridgeConnectorImpl          TRACE  BRIDGE:Exit sendRequest(), IOException=End of stream reading message

2022-11-15 19:28:03.960 [main] c.a.s.a.b.i.BridgeConnectorImpl          TRACE  BRIDGE:Exit sendRequest(), IOException=Different versions on server (21.0) and client (12.3.).

Cause

LDAP Sync and Automation Engine needed to be on the same version

Resolution

Looking at the snippet sent, LDAP.Sync has not been upgraded.

The error message:

"2022-11-15 19:28:03.960 [main] c.a.s.a.b.i.BridgeConnectorImpl          TRACE  BRIDGE:Exit sendRequest(), IOException=Different versions on server (21.0) and client (12.3.)."

Is stating that the LDAP.Sync version is lower than the system version which is at 21.0. 

To resolve this LDAP.Sync must be upgraded to match the Automation Engine version.  In the case above, 21.0 is needed which can be found here: https://downloads.automic.com/downloads/advanced_mode&selected_tab=id_search-result-files&lifecycle_entity_id=1409143059253&major_version_id=1642064887326%2C1660210974508%2C1656337838436%2C1653304169438%2C1637003273101%2C1648591279187%2C1646171149329%2C1627281031434%2C1637005649830%2C1627281031351%2C1631857933175%2C1585553688489&component_id=1602489357672&search=

Please note with an upgrade from 12.3 to 21.0, the LDAP.Sync needs to point to a JCP WS.PORT instead of the CP port.
