    Also, when I try to use the command line (ipa user-mod or

    or allow me for any input. I can see the following in krb5kdc.log ,

    The output of "certutil -L -d /etc/httpd/alias -n Server-Cert"
    confirms that certificate is expired as given below.

    I went through the documentations to check how to renew the
    expired certs but it seems to be confusing and different across
    versions. Could someone please help me out by suggesting which is
    the best way to achieve this ? Any help would be greatly
    appreciated as I am unable to perform any task on the IPA server
    now because of this.

    I suggest following the mod_nss suggestion to allow it to start and
    use the expired cert while you attempt to figure this out.

    Thanks indeed for the suggestion. I will consider this. But can
    anyone point me the steps to renew certificate from the expired one ?

    Thankds and regards,

Lets start with figuring out why certmonger didn't do this for you:

Can you run as root: ipa-getcert list

You should have something like:

Request ID '20111215203350':
        status: MONITORING
        stuck: no
key pair storage: type=NSSDB,location='/etc/httpd/alias',nickname='Server-Cert',token='NSS Certificate DB',pinfile='/etc/httpd/alias/pwdfile.txt' certificate: type=NSSDB,location='/etc/httpd/alias',nickname='Server-Cert',token='NSS Certificate DB'
        CA: IPA
        issuer: CN=EXAMPLE.COM Certificate Authority
        expires: 2021-12-15 20:33:50 UTC
        track: yes
        auto-renew: yes

If you don't have something like this then perhaps the easiest way to get it renewed is to tell certmonger to track it. First, look at your current database, it should look something like:

# certutil -L -d /etc/httpd/alias

Server-Cert                                                  u,u,u
EXAMPLE.COM IPA CA                                           CTu,u,Cu
Signing-Cert                                                 u,u,u

Now track it

# ipa-getcert start-tracking -d /etc/httpd/alias -n Server-Cert

Use ipa-getcert list to track the status of the renewal. Once it has been completed you can reset the EnforceValidCerts option and restart Apache.

If certmonger is already tracking the cert and the renewal has failed then please provide the ipa-getcert list output.
