Some key sticking points I wan to point out:

- Check your existing users in AD to make sure you provide all required attributes

- OperationNotSupportedException usually indicates that something required is missing or password requirements are not met. If you are getting this exception change userAccountControl value to 2 - user dissabled. This will allow user creation with out password verification.

- Password has to bent to AD in unicode format.

Here is portion of the spring config that pertains to the bean:

	<bean id="ldapContextSource" class="org.springframework.ldap.core.support.LdapContextSource">
		<property name="url" value="${ldap.url}" />
		<property name="base" value="${ldap.base}" />
		<property name="userDn" value="${ldap.admin.bind.userdn}" />
		<property name="password" value="${ldap.admin.bind.password}" />
	</bean>

	<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
		<property name="contextSource" ref="ldapContextSource" />
	</bean>

	<bean id="ldapUserDAO" class="com.trx.wfm.model.dao.LdapUserDAO">
		<property name="ldapTemplate" ref="ldapTemplate" />
		<property name="ldapReadonly" value="${ldap.readonly}" />
		<property name="ldapBase" value="${ldap.base}" />
	</bean>

ldap.base points to the OU where the users are created. This simplifies the operations, since I am checking for users only on this branch of the tree and adding them there too.

And on more point - to change anythign in AD you need to go via secure connection ldaps://your.ldap.server:636. Most likly you will get an certificate error, since my server’s is self signed, so use keytool provided in java home/bin directory to import security certificates into key store. Make sure you specify the path of they keystore file! I did it wihout the keystore file and my app was still getting exceptions. You can provide they keystore location to java as VM startup parameter (RTFM).

I am ordering my projects according to the priority and completion potential. I will spend time only on one of them until it is finished. I think a lot of technical people have the problem with polishing the product and never realizing that is does not have to be perfect. Once it is working, we need to focus on marketing and selling it. I know I sometimes suffer from this perfection paralysis.

So focus, focus and one more time focus. Do not let your eye off the ball.

On another note, we are filing our first eviction in 3 years or real estate investing. That is a great track record, but I rather not do it. Sometimes you just have no choice. To have even a slight chance of getting our money we have to go to court. I feel for the family that has to move out, but we can not afford to run a charity.

I came to a realisation that the only way to freedom is internet business. Real estate is great, but you have to be there all teh time. You need to go see houses, buyers and sellers. Unless, of course, you are a multi millionaire and can just buy and sell skyscrapers and shopping mals or big apartment buildings.

To have freedom to travel and work from anywhere I need to be location independent. I have this dream of renting and RV and driving around the USA one summer. To make this work, I need a business that will run itself with minimum involvement form me. The only way I see it - take it to the internet. I allready have multiple websites up and running, but only one has potential to bring any substantial income this year. So now I have crafted a plan to launch 2 products taht I can sell online. And one of them has the lucrative “monthly subscibtion” feature.

I am working on the first one already. I will be releasing a Beta pretty soon. And the best part of it - I am planing on giving the base version out for free.

So here it is. How that I have promissed to you, that I am gonna do it, I have no other choise, but to do it.

HI,

I am back from the long break! inthe time I was away I had a life changing experience - birth of my daughter Luka.  It is truly a life changing experience. Now that we are over the initial shock and trying to adjust to new way of life (read - no sleep) I will be getting back to online marketing.

How should I go about promoting this website? I will email all fellow investors I know to add the houses they have to it. That should add couple  hundred houses. How would you go about promoting it for buyers?

My plan:

1. place adds on craigslist
2. respond to adds on craigslist
3. need more ideas…

Anybody has a good idea how to get trafic?

Tomas

Has anybody added openid to their website and found it to be the time well spent?

First one was for life coach. I spent couple evenings setting it up. It is running on wordpress platform. Do you realize that wordpress is not only for blogging? If you need update the content constantly, wordpress is an excellent choice. So there is that, just initial content, need to do much more search engine optimization…..

Second one was created, because I felt a vacuum in one particular market segment. It was homes for sale with owner financing or rent to own programs. In essence a site where people can find homes for sale without bank qualifying. I found couple of those, but they where localized, none had enough homes to be effective. So here it is - a national rent to own and owner financed homes for sale website.

It still is in beta and I am adding features as I go….. and waiting for google to show up. Once it is in the index what would be the best way to promote it?

I just spent good half an hour searching for online marketing blogs. Unfortunately all I was able to find is a bunch of crap. Pardon my French. Almost all the blogs I found where so overloaded with ads, had almost no information about online marketing and tried to sell me something. I realize everyone needs to make a living, but what happened to just sharing information?

Has anyone found a decent blog about online marketing?
