I got the following message The STARTTLS certificate will expire soon
. Now I tried to create new certificates, but currently the old ones are still used.
Questions:
- Can I backup the old certificate somehow (in case I remove one but missed a thing)?
- Does a service can be assigned to only one certificate? (I always get the notice that another certificate is getting priority) And can I delete the other one with the same assigned service?
- Can I delete certificates with the status
DateInvalid
? - Can I delete certificates with no services assigned?
Now the certificates which have to be replaced.
Case 1:
Old one:
AccessRules : {System.Security.AccessControl.CryptoKeyAccessRule, System
.Security.AccessControl.CryptoKeyAccessRule, System.Securi
ty.AccessControl.CryptoKeyAccessRule}
CertificateDomains : {Sites, servername.domain.local}
HasPrivateKey : True
IsSelfSigned : False
Issuer : CN=domain-servername-CA
NotAfter : 24.08.2012 08:55:23
NotBefore : 25.08.2010 08:55:23
PublicKeySize : 2048
RootCAType : Registry
SerialNumber : 486D0BC600000000500C
Services : IIS, SMTP
Status : Valid
Subject : CN=Sites
Thumbprint : 5XY3E4589CDEE54C1FB9C1745XC351D8C74D
Replacement:
AccessRules : {System.Security.AccessControl.CryptoKeyAccessRule, System
.Security.AccessControl.CryptoKeyAccessRule, System.Securi
ty.AccessControl.CryptoKeyAccessRule, System.Security.Acce
ssControl.CryptoKeyAccessRule}
CertificateDomains : {Sites, servername.domain.local}
HasPrivateKey : True
IsSelfSigned : True
Issuer : CN=Sites
NotAfter : 30.07.2017 12:41:34
NotBefore : 30.07.2012 12:41:34
PublicKeySize : 2048
RootCAType : None
SerialNumber : AAFC94772E6BFF8E4AE9812226240927
Services : IIS, SMTP
Status : Valid
Subject : CN=Sites
Thumbprint : 98732EASYDFGC4336430DEDE729EE0D575C0
Notable differences:
- self signed is true
- issuer is different
- two times: System.Security.AccessControl.CryptoKeyAccessRule
Case 2:
Old one:
AccessRules : {System.Security.AccessControl.CryptoKeyAccessRule, System
.Security.AccessControl.CryptoKeyAccessRule, System.Securi
ty.AccessControl.CryptoKeyAccessRule}
CertificateDomains : {mail.domain.com, many further domains}
HasPrivateKey : True
IsSelfSigned : False
Issuer : CN=servername-domain-CA
NotAfter : 17.08.2012 15:37:50
NotBefore : 18.08.2010 15:37:50
PublicKeySize : 2048
RootCAType : Registry
SerialNumber : 56329D6600000000000D
Services : IMAP, POP, SMTP
Status : Valid
Subject : CN=mail.domain.com, OU=Technics, O=Organisation, L=Location, C
=CC
Thumbprint : A8329DCD493FLIE2E3C9AF2E7577ADD6EF669
Replacement:
AccessRules : {System.Security.AccessControl.CryptoKeyAccessRule, System
.Security.AccessControl.CryptoKeyAccessRule, System.Securi
ty.AccessControl.CryptoKeyAccessRule, System.Security.Acce
ssControl.CryptoKeyAccessRule}
CertificateDomains : {mail.domain.com, many further domains}
HasPrivateKey : True
IsSelfSigned : True
Issuer : C=CC, L=Location, O=Organisation, OU=Technics, CN=mail.domain
.com

.com
Thumbprint : 83EKDFKLIO483ZH94F2C84B7DA16DC3C05875D
Notable differences:
- self signed is true
- issuer is different
- two times: System.Security.AccessControl.CryptoKeyAccessRule
- order of subject is different
Now my question to these certificates:
- Can I ignore the differences?
- For the replacements: Can I delete the old certificates and all would still work (e.g. Outlook Web Access)?
