SVN committing not possible ATM?

[Marko Käning]

I just now couldn’t commit to the SVN server:

---
$ svn ci -m "gwenhywfar4-devel: update to 4.16.0beta"
Sending        Portfile
Transmitting file data .svn: E175002: Commit failed (details follow):
svn: E175002: Unexpected server error 500 'Internal Server Error' on '/repository/macports/!svn/txr/154147-3axv/trunk/dports/devel/gwenhywfar4/Portfile’
---

Very likely, I am just not authenticating properly. What do I have to change to make this work again?

Greets,
Marko
