[Feature Request] Support for Bearer Token/OpenId Authentication in TortoiseSVN

[Ariel Sandberg-Maitland]

Description: I have migrated an SVN server from LDAP Authentication to OpenID Connect using the mod_auth_openidc module in Apache2. The configuration works well with modern web browsers, allowing users to authenticate via Azure EntraId. However, when using the TortoiseSVN client, I encounter an authentication error.

Steps to Reproduce:

1. Configure Apache2 with mod_auth_openidc for OpenID Connect authentication.
2. Attempt to access the SVN repository using a modern web browser (works as expected).
3. Attempt to access the SVN repository using TortoiseSVN client (fails with authentication error).

Expected Result: TortoiseSVN should support bearer token authentication, allowing users to authenticate via OpenID Connect.

Actual Result: TortoiseSVN fails to authenticate, displaying an error: "Error running context: An error occurred during authentication."

Environment:

• Device: PC
• Operating System: Windows 10
• TortoiseSVN Version: [Specify version]

Additional Information:

<Location /svn>
  DAV svn
  SVNParentPath /svn
  SVNPathAuthz off
  AuthName "Subversion Server"
  AuthType openid-connect
  Require valid-user
  AllowOverride All
  Order allow,deny
  Allow from all
  AuthzSVNAccessFile "/etc/svnaccess/svnaccess.list"
</Location>

• Attempted to modify %appdata%/Subversion/servers file to include:

[groups]
mygroup1 = *.domain.tld

[mygroup1]
http-auth-types=basic,digest,negotiate

However, this did not resolve the issue as OpenID Connect uses bearer token authentication.

Request: Could you confirm that bearer token/OpenID authentication is not supported yet? I appreciate the hard work on TortoiseSVN development community. Please consider adding support for bearer token authentication This would greatly help users with modern authentication needs.

this would have to be implementec in the svn library, not in TSVN.

So you have to ask for this on the subversion mailing list:
