## PulseUno vaults

The following issues and limitations exist when working with the Vault server.

Known Issue | Description

## Git functionality

The following issues and limitations exist when working with the PulseUno Git server.

Functionality | Issue
--- | ---
Serena SSO/CAC | The Git server is not supported when using Serena SSO/CAC. To work with the Git server, choose an authentication scheme other than Serena SSO.
Signed commits and server-side merge | Defining a branch policy that enforces signed commits in a particular branch may prevent server-side merges of pull requests to that branch. This behavior is expected, as the server-side merge doesn't have access to your private GPG key to sign commits on your behalf. Workaround: Merge locally with a signature and push.
