Client authentication with Kerberos ticket

From: Yves Martin <yves.martin_at_elca.ch>

 I'm currently deploying Subversion (1.2.3 on Debian Linux server)
 with Apache2/mod_dav/svn/mod_auth_krb
 and a svn client in version 1.4.2 (Linux)

 If I allow kerberos password (KrbMethodK5Passwd on)
 it works but the client asks me for the password each time.

 If I disable kerberos password (KrbMethodK5Passwd on)
 with KrbMethodNegotiate on,
 the client fails directly without trying my ticket, just
 successfully created with kinit (checked with klist).

 I have found no tutorial or FAQ concerning svn+kerberos+ticket
 With neon debug messages enabled, but it does not help me (see below).
 I have compiled neon lib (client) with gssapi. But is it enough ?

 Thank you for any hint to get svn and Kerberos working together
 (either with a ticket or my password cached - but I prefer the ticket)
