## Introduction
|
||
|
|
||
|
[ClickHouse] currently does not have any integration with [LDAP].
|
||
|
As the initial step in integrating with [LDAP] this software requirements specification covers
|
||
|
only the requirements to enable authentication of users using an [LDAP] server.
|
||
|
|
||
|
## Terminology
|
||
|
|
||
|
* **CA** -
|
||
|
Certificate Authority ([CA])
|
||
|
|
||
|
* **LDAP** -
|
||
|
Lightweight Directory Access Protocol ([LDAP])
|
||
|
|
||
