Steve, THANKS! I got a new cert, and it's now working. They thought they had things correctly configured, but with the info you provided, we got things straightened out. Here's one of the working ones: E:\OpenSSL\bin>openssl x509 -in user5-atest3.cer -text -noout Certificate: Data: Version: 3 (0x2) Serial Number: a7:75:bc:83:8f:eb:2c:8a:46:3f:dd:66:af:62:5a:b9 Signature Algorithm: sha1WithRSAEncryption Issuer: C=US, O=ATest3 Org, OU=ATest3 OU, CN=ATest3 ROOT CA/emailAddress [EMAIL PROTECTED] Validity Not Before: Mar 1 04:09:50 2005 GMT Not After : Feb 27 09:20:02 2012 GMT Subject: C=US, O=ATest3 Org, OU=ATest3 OU, CN=USER5-ATEST3/emailAddress= [EMAIL PROTECTED] Subject Public Key Info: Public Key Algorithm: rsaEncryption RSA Public Key: (1024 bit) Modulus (1024 bit): 00:f2:f3:fc:c6:64:cf:e2:fc:9c:76:fc:6c:da:d6: 8f:96:04:4e:1a:e8:46:3a:97:2e:11:de:14:af:00: . <snip> . 3a:b8:94:28:5d:ca:6e:23:f9:79:84:74:83:98:49: 13:52:e7:1b:f3:fb:96:43:01 Exponent: 65537 (0x10001) X509v3 extensions: X509v3 Key Usage: critical Digital Signature Netscape Cert Type: SSL Client X509v3 Authority Key Identifier: keyid:55:90:95:CC:D3:E5:3B:7C:5C:41:27:DB:1F:30:04:A4:DE:A3:D4:B A X509v3 Subject Key Identifier: 77:6A:F2:84:B1:30:D3:D4:08:AD:11:00:CE:D5:B6:82:E2:77:04:BD Signature Algorithm: sha1WithRSAEncryption 91:89:74:d8:4b:75:28:4f:06:ab:b4:5d:a6:a7:8b:3d:5e:e4: 91:09:86:fa:ed:eb:ee:5f:0e:41:ea:25:2e:38:b1:de:20:2c: . <snip> . 82:d4:70:f8:cf:9a:89:22:aa:b6:f8:0e:38:41:19:12:99:98: 88:c7 Jim ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
