If you found a bug in python-ldap, or would request a new feature,
this is the place to let us know.

Please describe the issue and your environment here.

Issue description:

The syncrepl code included with python-ldap only functions when there is a single contectCSN value in use. If the LDAP system is multi-provider, only one CSN value is stored, causing the code to always execute a REFRESH on startup.

Steps to reproduce:

Set up a multi-provider environment, use the syncrepl API to execute refresh

Operating system:

linux

Python version:
3.10.12

python-ldap version:
3.4.3
