I believe I have discovered a potential problem with MS2MIT. Using the MS2MIT from the 2.5.0.1 build, when I import the tgt using ms2mit, I get: Ticket cache: API:krb5cc Default principal: pierre@MTLW2KTEST.MONTREAL.HCL.COM Valid starting Expires Service principal 03/01/04 10:03:31 03/01/04 20:03:31 krbtgt/MTLW2KTEST.MONTREAL.HCL.COM@MTLW2KTEST.MONTREAL.HCL.COM renew until 03/08/04 10:03:31, Etype (skey, tkt): ArcFour with HMAC/md5, ArcFour with HMAC/md5 Kerberos 4 ticket cache: API:krb4cc klist: No ticket file (tf_util) Using the MS2MIT from 2.1.2, when I import the tgt using ms2mit, I get: Ticket cache: API:krb5cc Default principal: pierre@MTLW2KTEST.MONTREAL.HCL.COM Valid starting Expires Service principal 03/01/04 10:12:04 03/01/04 20:03:31 krbtgt/MTLW2KTEST.MONTREAL.HCL.COM@MTLW2KTEST.MONTREAL.HCL.COM renew until 03/08/04 10:03:31, Etype (skey, tkt): DES cbc mode with CRC-32, DES cbc mode with CRC-32 Kerberos 4 ticket cache: API:krb4cc klist: No ticket file (tf_util) I have attached my krb5.ini which shows the default encryption types as: default_tgs_enctypes = des-cbc-crc default_tkt_enctypes = des-cbc-crc The config file for the unix server is also attached. Clearly, ms2mit from 2.5.0.1 gets rc4 tickets instead of des-cbc-crc which is what is specified in the krb5.ini. If I get RC4 tickets, then I cannot authenticate to my unix server which is expecting des-cbc-crc... Pierre Goyette Hummingbird, Ltd.
