On April 24, 2025, the ACCESS User Registry will be reconfigured to remove the LDAP Provisioner. No downtime is expected.

LDAP was previously used for storing ACCESS User Registry attributes for consumption by third party services such as CILogon and the ACCESS SSH Pubkey Downloader. On September 10, 2024, an alternate provisioner using DynamoDB was deployed. (DynamoDB is an AWS-managed serverless NoSQL service with high performance and a 99.999% SLA.) CILogon has been using the DynamoDB deployment since that time. On April 9, 2025, the ACCESS SSH Pubkey Downloader was reconfigured to also use the DynamoDB deployment. 

After the ACCESS User Registry has been reconfigured to remove the LDAP Provisioner, there will be no services using the ACCESS User Registry LDAP servers, so they will be decommissioned.
