Symptoms
Certificate-based VDFS replication may halt when the replication certificate expires. The following note will be displayed on the Replication tab in the VisualSVN Server Properties:
The following error is logged to the VisualSVN Server Replication event log on the master server:
Details:
A required certificate is not within its validity period when verifying against the current system clock or the timestamp in the signed file.
Cause
The replication certificates installed on master and slave servers must be valid and not expired for the VDFS replication to work over certificate-based authentication. When the replication certificate expires it becomes invalid.
Resolution
The expired certificate should be replaced with a valid and trusted certificate. For further information, read the article KB121: Understanding Replication Certificates.
