Disable Lock Screen
OK, I was playing around and set up the lock screen on my TP. While this could potentially be a nice feature, I decided it was more cumbersome than helpful.
Despite going through the security menu and seeing the settings for disabling the lock screen, which are grayed out, I simply can't find a way to disable it.

As I look at this with a little more clarity, I think I may have some information that could give some direction on how I might be able to sort this out:
In the area next to "None" in the Settings Lock Screen menu, it says, "Disabled by administrator, encryption policy, or credential storage."
I am running the following applications that I suspect may be the culprit:
System Tuner
Super user
I have gone through both looking for a setting or other information that might reveal what has disabled this setting, but nothing jumps out at me.
Again, any suggestions?
I did restore from a backup made prior to invoking this setting, along with wiping the Dalvik cache. No joy. I am wondering if I should do a complete restore to factory defaults and then restore my backup.

See if a program has admin rights and if so uncheck it.
I'm looking at this in my GB phone so it may be a little different in CM9.
I looked at that previously and it is greyed out and shows no device administrators. When I saw this I attempted to add one but it wouldn't allow me to.
I would add that I am a net admin with a working knowledge of permissions and rights relative to a Windows environment, so this is not unfamiliar territory for me. I'm just not familiar with Android....

Figured it out.
I went into "Profiles" and looked at the settings. In the profile settings at the bottom is an entry for "System settings -Lock screen mode". You can choose several settings, one of which is disable.

Once I applied it, no more lock screen!
Again, thank to those who made suggestions!

Hi Dan,
I'm stuck with exactly the same problem. Where is this "Profiles" that you've used to solve it? I've looked for it on my phone but I can't find it.
I had this exact problem, which turned out to be the result of a VPN profile I had set up (though I was never actively using it). Deleting all VPN profiles made all the screen lock choices visible again.

Dear Charles,
I deleted all VPN profiles. This is a very useful for me.
Thanks.. Thanks.. Thanks
A lot of business email wifi accounts will do this, too. Anything that has an encryption certificate that permanently resides in your phone will cause the problem.
You can delete the VPN accounts or email accounts, but that only works if you don't need the VPN or email account. If you need those things, you have to fix it some other way.
Keep in mind if you're doing this on a business phone, you may be putting your company's data at risk. Since you're bypassing a company policy/procedure, it's your responsibility.

Thank you so much. Yesterday I wanted to remove the pattern lock to swipe on my Galaxy S2. But the first three options (none,swipe & facelock) were greyed. (saying its disabled by device administrator.) Never happend that before.
Luckily i found your post. Deleted the vpn profiles I'd created a few days ago. And voila!... All the options are available now.
I had this all buggered up with a m.google.com exchange set up with the the sammy email app checking my google apps email account. Fortunately, I am the google apps admin for my company so I could change the settings in google apps.
But, then after much trouble playing with screenlock setting, I discovered that I must decrypt the SD card to release the credentials...
So, if all else fails check the SD card and see if its encrypted. Worked for me.

If your Screen Lock option under Screen Security has greyd OUT " NONE , SLIDE & Face Unlock option then simply go to --- > Settings ---> go to Security --> scroll down to the last option Clear Credentials Press OK and you will have all the options back in screen lock.
I tried installing a CA cert to receive my company emails and this greyed out the "Screen lock: None" option with the message "disabled by administrator encryption policy..."on my HTC One X. Here is what I tried.
1) I immediately removed the certificates I had just installed, the issue was not resolved.
2) Thought a reboot of the phone would help but even that didn't work.
3) Under Settings => Security => Credential Storage, there is a button to "Clear Credentials". I clicked on that praying that none of the System credentials would be wiped out. It is a new phone, so I didn't mind resetting to factory settings anyway. Looks like the System credentials are still there and my problem has been resolved. I hope this helps someone out there.
recently they changed to microsoft exchange at work, and when I tried to add my new work email account on my CM9-touchpad, it asked me if it was ok to modify the security settings, as in password unlock, and encryption. I declined, and added the email account as a generic account (no calendar/phonebook integration, etc). Small price to pay for freedom... yours may be a similar issue...

I just managed to resolve this on my S3 after looking for a solution in other forums:
This was the problem:
- Inserted a new SD card
- Formated the card
- Now I could not get any other unlock method to activate... not even after clearing the admin controls and credentials
And these are the steps I took to resolve it (In "Settings -> Security"):
- Encrypted the SD card (everything)
- Decrypted the SD card (again, everything)
- Made sure phone is decrypted again
- Done! unlock options became available again
