Achim@beren [~]$ klist • Creating the HTTP service principal for beren.grolmsnet.de For every kerberized host you have to create a service principal on the KDC.When using Windows 2000 that means you have to • create a dummyaccount in Windows Domain GROLMSNET.DE. It is used like a machine account. In this example the name of dummyaccount is kerbdummy1. • login to the DC ulmo and use the Windows commandline tool ktpass to map the dummyaccount kerbdummy1 to the serviceprincipal HTTP/beren.grolmsnet.de@GROLMSNET.DE. You need that serviceprincipal to kerberize host beren. Ensure you use the canonical hostname of beren.grolmsnet.de in ktpass command. That means • if beren.grolmsnet.de is a CNAME-record use the DNS-name the CNAME record points to.

• if beren.grolmsnet.de is an A-record ensure the corresponding PTR record points to beren.grolmsnet.de, too. (In other words: reverse-DNS-lookup of beren.grolmsnet.de's IP address has to point to beren.grolmsnet.de Use ktpass options as describe in the table below: Windows 2008 R2 DC Windows 2003 SP1 DC Windows 2003 DC Windows 2000 DC encryption type AES256 (not supported by WinXP) RC4 DES (experts say DES is weak) DES (experts say DES is weak) ktpass command. C: >ktpass -princ HTTP/beren.grolmsnet.de@GROLMSNET.DE -mapuser kerbdummy1 -crypto DES-CBC-MD5 -pass longlongpassword -out c: temp berenkeytab ktpass description KDC's kvno ticket behavior sends a ticket with a Key Version Number (KVNO). Ensure you have the correct kvno in your keytabfile, if the ticket has a kvno it must match!

I've been working on some linux hosted sites within windows domains recently and found it. The Kerberos installation guide for Ubuntu Server can be found at. To install the apache module required for the web server to communicate with. Jun 8, 2018 - It's necessarry to be running Windows Active Directory in your LAN. This example. Root@www:~# apt -y install libapache2-mod-auth-kerb.

Sends no ticket with Key Version Number (KVNO) ktpass keytab behavior kvno is properly exported to keytabfile kvno is not properly exported to keytabfile, kvno-value in keytab is 1 for each run of ktpass. No problem when running ktpass one time, problem when ktpass is run more then one time because every run of ktpass increases the kvno in KDC. Workaround is to use -kvno=x option of ktpass with x = actual kvno + 1 The ktpass command creates the pricipal HTTP/beren.grolmsnet.de@GROLMSNET.DE, maps it to AD account kerbdummy1 and exports it's key to the keytabfile c: temp berenkeytab. Copy that file to beren.grolmsnet.de, you will need it in the next step. Copy file c: temp berenkeytab from DC ulmoto the location where it sould reside on host beren - in our example /usr/local/apache/conf/http_beren.krb5keytab An alternate way to create the needed keytabfile is from Dan Perry. This tool you can use on your Unix box to create a keytab. Best keygen etka 74 2016 free and torrent downloads.
