GSS/kerberos credential mapping

2009-10-27 Thread Mike Gerdts
I'm trying to understand the feasibility of leveraging Kerberos provided by an existing Active Directory implementation for use with Solaris machines. The tricky part of it is that the the user names chosen in AD are all 9-digit numbers, which are not compatible with OpenSolaris, Solaris, etc. I'

GSS/kerberos credential mapping

2009-10-27 Thread Henry B. Hotz
AFAIK, all current, common mapping mech's are many-to-one --- the one being the unix username. The other direction is not properly defined. I forget if the AD UPN is multi-valued or not. If so, then it offers no particular solution for the problem. Even if that attribute is single-valued

How to change the signature algorithm from MD5 to SHA1 in OpenSSL

2009-10-27 Thread Dan Anderson
If you're going to go through the trouble of changing the signature algorithm from MD5, choose a strong algorithm instead of another weak one. SHA1, although not as weak as MD5, is not recommended either. See this comnment from NIST: "NIST Comments on Cryptanalytic Attacks on SHA-1" http://cs

How to change the signature algorithm from MD5 to SHA1 in OpenSSL

2009-10-27 Thread Wolfgang Ley
Hi, this has been answered yesterday. Please see the forum postings. You'll have to add the "default_md=sha1" line to the [ req ] section in the config file (not just modify the default_md entry in the ca section as this one is not used for the req command). In addition: You're not running Ope
