Uhmm,... I have no idea at all *g*,...
Currently I've set up the following mod_dav_svn configuration (see
attachments).
And what I wanted to do now was,... to take away the AuthType Basic
stuff at all,... and make the whole autorization / authentication thing
using the SSL client certificates only (Thought a 4096 bit key within
the certificates should be much better than the passwords from Authtype
basic ;) ).
But my problem is: If I take the whole AuthType Basic AuthUserFile etc.
away,... I cannot set up my AuthzSVNAccessFile /srv/svn/access because I
have to use the "user-names" there, e.g.:
[myFirstRepos:/]
user1=rw
user3=
user2=r
and so on,.. but how can I integrate information from the certificates
there? And which one (Name, Serial Number, etc) would be the best (that
means an information that has been signed by my CA Certificate and is
thus secured to be unique)?
Thanks and regards,
cam.

# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is send or allowed to received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is send and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.
