An alternative to custom objectclasses: the extensibleobject

I’ve spent a decade designing and implementing LDAP directories, but only recently had the opportunity to reflect on the big picture.

Cleanup of referrals from old replication agreements in Sun Directory

A brief note on curing an issue I’ve run into on Sun Directory Server. We recently retired a couple of master directories in the environment.

Use wget to download Oracle patches directly to the server

My colleague Mike Zeece found an article on Michael Brown’s blog that describes how to do this.

Ntpd on Solaris 10

This is easy.
Here are the steps (all done as root):
1. Copy /etc/inet/ntp.server to /etc/inet/ntp.conf, and then edit ntp.conf to comment out the “server” and “fudge” lines. Add a line to the bottom of the file,

touch /var/ntp/ntp.drift
3. Initialize the ntpd service,
svcadm enable svc:/network/ntp

Reading SSL certificates with openssl

This will be a very basic post.
Say you have three SSL certificates:
cert1.pem
cert2.der
cert3.cer
The first certificate is probably in PEM, or Privacy Enhanced Mail, format. Basically all this means is that the certificate text has been Base64 encoded.
The second is most likely in DER, Distinguished Encoding Rules, format. This is a subset of BER, Basic Encoding Rules, [...]
