Hi All,

Here's my 12th tip in the "OpenLDAP Quick Tips" series:

"You want to switch from slapd.conf to the configuration backend to slapd":

The config backend is backward compatible with the older slapd.conf(5)
file but provides the ability to change the configuration dynamically
at runtime. If slapd is run with only a slapd.conf file dynamic changes
will be allowed but they will not persist across a server restart.
Dynamic changes are only saved when slapd is running from a slapd.d
configuration directory.

The following should be getting you very excited:

provides the ability to change the configuration dynamically
at runtime.

Dear All,

I'd like to get some examples written up for:

http://www.openldap.org/doc/admin24/appendix-deployments.html

If anyone is interested and allowed to share some information, I'd
love to hear from you.

The more strange the setup the better!

Many thanks,

Gavin.

Hi All,

Here's my 11th tip in the "OpenLDAP Quick Tips" series:

"You want to make sure you have the correct indices configured for the best performance":

It's easy to discover when you do not have the correct indices set by checking your ldap^[?] log. If you see something similar to:

Grab it whilst it's hot!

Hi All,

Here's my 10th tip in the "OpenLDAP Quick Tips" series:

"You want to stay up to date with the latest version of OpenLDAP to benefit from bug fixes":

There's never been a better time to upgrade to the 2.4 series. It's actually very easy. If there haven't been any significant core changes between releases (excluding a 2.3.x to 2.4.x upgrade), then you can easily just install a new version on top of the existing one and restart.

If there has been a Berkeley DB change or any form data storage change (indexing etc.) then you should follow these steps:

1. Stop the current server when convenient
2. slapcat the current data out
3. Clear out the current data directory (/usr/local/var/openldap-data/) leaving DB_CONFIG in place
4. Perform the software upgrades
5. slapadd the exported data back into the directory
6. Start the server

It is recommended to do the above anyway, just to make sure as you can always start fresh with exported data.

Obviously this doesn't cater for any complicated deployments like MirrorMode or N-Way Multi-Master, but should you need advice or help, you can use either commercial support or community support to help you....or contact Suretec.

Thanks,

Gavin.

Hi All,

Here's my 9th tip in the "OpenLDAP Quick Tips" series:

"You want to edit data in your directory server, but only have command line access":

When you want to quickly edit some data and don't want to use the ldap^[?]* command line tools that come with OpenLDAP, why not grab ldapvi:

ldapvi is an interactive LDAP^[?] client for Unix terminals. Using it, you can update LDAP entries with a text editor.
Think of it as vipw(1) for LDAP.

Thanks,

Gavin.

Hi All,

Here's my 8th tip in the "OpenLDAP Quick Tips" series:

"You want to create your own LDAP^[?] Schema for your directory server":

The golden rule:

Under no circumstances should you hijack name space belonging to others!

When you want to extend or create one yourself, get your own OID or PEN using the Private Enterprise Number (PEN) Request Template.

It takes around 2 weeks and you will then always be listed on the PRIVATE ENTERPRISE NUMBERS page if you forget the number and it means your namespace will never clash with others.

Anyone in the LDAP field that is worth their salt should be listed, we are (Suretec Systems Ltd.).

Thanks,

Gavin.
