Hyperlinks in CRM 2011 Rollup 12 do not work in Safari

One of my co-workers who use Safari way more than I do pointed out today that he couldn’t click links in Safari on his Macbook Pro running Mountain Lion. I was able to reproduce this as well in my Safari. Starting my debugging I noticed if I opened the developer console the links worked, which didn’t help me much. I made sure popups where disabled and no luck as well. Finally thinking maybe I had an extension in Safari causing it, I tried disabling all extensions. Again nothing was working to resolve the issue.

By chance I happen to stumble on a workaround at least. In the progress of debugging this, I changed my user agent, the page refreshed and it worked. I realized something, after opening the debug console it refreshed the page as well. So closing Safari and opening it again, I again came upon the page and couldn’t open any links in CRM. I hit F5 and let the page refresh. Once the refresh completed all the links worked. Not sure why, but a refresh seems to resolve this.

Note: My co-worker couldn’t use F5 in his Safari. I believe I remapped it at one point in Safari as its F5 in all other browsers and just like it that way. I believe the default is Apple + R.

Chrome closes with CRM 2011 Rollup 12

Doing more testing with CRM 2011 Rollup 12, I found out that Chrome was self closing when I logged into CRM. This is very annoying, but having worked with CRM before in IE, I knew what this was. By chance I was able to verify it by going to the CRM url and changing the last part of the url to /main.aspx. I got a notification that a popup was blocked. Sure enough, after I added the crm address to the popup blocker exception list, no more self closing windows.

Update 2/14/13: Also should note that this affects Safari as well. Popupblocker’s cause quite a problem with CRM and there is no notification what it is about to do. I find the fact that CRM needs to launch into its own window a pain. I personally have it in a pinned tab in Chrome. I don’t worry about it and when I need CRM its there and not on some other obscure window.

Preventing access to drives on Windows 7

I added boot camp to one of my macs and happy found that that Windows 7 supports reading HFS drives. Which means it had access to my Mac OS X installation. Sadly it didn’t keep the user permissions setup and I could see everything from all users. Not acceptable for a family used computer.

So some google searches did bring up some options, however I found that all of them alone don’t resolve the issue completely.

The first thing I found suggested using “gpedit.msc” to add policy in User Configuration -> Administrative Templates -> Windows Components -> Windows Explorer in the “Prevent access to drives from My Computer” policy. However this had two limitations here. First off it applies to the current local user only and secondly it only did drives A-D. Which doesn’t help me with drive E.

Now, I can open “mmc”, go to add a snap in, select Group policy editor, click browse and then the users tab to set it to non administrators. However the secondary limitation was still the problem. I needed to do a non default drive that the group policy editor didn’t support. Which makes it almost useless.

Another solution I found was to modify the windows registry to do this. HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer may contain a dword called “NoViewOnDrive”. This is perfect for what I want as I can limit it to other drives. A article on how to geek explained how the data was represented. So this works out for me.

However that solution had the same problem as first time where it only the current user. So after more searches not turning up anything useful I found a solution that works. By using the mmc I created above to add a policy for non administrators, it added that data into the registry. I simply used the find function to locate “NoViewOnDrive”. After some searches, I located it.

I do want to mention I did close the mmc I was using and opened the registry editor before. Data may be outdated otherwise and may not update. But it was simple to do this after which as I modified the value to match what I wanted. Now it appears to be working just fine for non administrators and is preventing access to the drive. A little more work than I wish I would of had to do in order to accomplish this, but it got the job done.

There is a similar dword in the registry called NoDrives. This simply hides the drives and does not prevent access to them. I left the drive visible as it really doesn’t bother me to see it. I just needed to prevent its unleashed access to the drive.

Mac OS X deleting users

I had a issue with my laptops video card dieing. None the less thanks to a class action lawsuit and some work by Apple, I have been able to get my video card replaced for free (See: http://support.apple.com/kb/TS2377). The nicest thing is that this is costing me $0 dollars to fix and ship back to me. Which is awesome and I am glad that Apple took the initiative to investigate the issue and help their customers.

Well while I wait for that to happen, I was smart enough to use Screen Sharing which still worked to pull the logs off my system. Upon trying this I found my user accounts missing. I had the root user enabled so I was able to still get in one way. So after recreating my user for now (I could recreate from a full backup I did just days before this), I put my logs on a thumb drive so I could look at them.

This is a snippet from the logs:

2/12/11 10:12:19 PM com.apple.loginwindow[59] 2011-02-12 22:12:19.113 ManagedClient[120:903] -xaDiskDisappeared: removing external account “_amavisd” with home “/var/virusmails” from DSLocal because disk disappeared.
2/12/11 10:12:19 PM com.apple.loginwindow[59] 2011-02-12 22:12:19.116 ManagedClient[120:903] MCXCDeleteAccount(): Trying to delete user id = 83

It wasn’t able to delete the system accounts, thankfully. However it did delete my account and a postgresql user account I created. Which I should of setup as a system account in the first place. No damage was done, just the user account deleted. All my data was still there and backed up.

Managed Client is apart of the OS X and is used to manage users in a server setting. That said my system was never setup in a server setting. But if I had to guess from the error log, it appears that when it losses connection to the server with the user account data, it is auto deleting users as a security precaution. Again I don’t have server setup or use this, which means it acted on the local users when it couldn’t load the data. Not a very smart idea of Apple to allow this for the local users though.

User data for the system is kept in /var/db/dslocal, which explains this. I also had a notice about anacron not being able to find its data in /var. So I am suspecting that my /var directory went corrupted during one of the restarts I did trying to diagnose the system.

2/12/11 10:12:09 PM com.18james.anacron[78] anacron: Can’t chdir to /var/spool/anacron: No such file or directory

Luckily I can restore everything lost in there off a backup and didn’t keep anything important in var. So it isn’t a major lose and I am glad I keep backups.  Unfortunately I wasn’t able to find very much information in searching around.  I didn’t feel like reading Apples 294 page PDF about user management to try and see if I could find anything about it.  A search of the document using some simple terms didn’t turn up anything.

As a final note, incase you are wondering, user accounts disappearing is happening to other OS X users, but none of them tried to look at the console log to see why. http://www.google.com/search?q=”mac+os+x”+user+account+disappeared

Disabling smb shares requires users password on snow leopard

I have just came across a very stupid idea that is implanted in OS X (Snow Leopard at least).  Believe me it doesn’t make sense as the computer administrator to have it setup this way.

When I go to sharing -> File Sharing and then open the options window.  I get options on setting up SMB for my windows machines on my network.  That is all fine and dandy, however if I want to disable it from sharing a users folder via smb (user authentication is required for the windows machine to access the files) I discovered that I must enter that users password to disable it.

To me this seems like a very bad idea from an administrators point of view.  I have no way without resetting the password to change this setting.  I didn’t even remember my postgresql users password as when I had set it up I generated a random password and never remembered it.

I can’t say whether hiding the user completely will make it disappear from that page.  I am too lazy to read up on how to do that for something that doesn’t even display on my login page (how I did that I can’t remember as I read a tutorial on how to setup postgresql on mac os x a long time ago).

So, I had to reset the password to something I could type in just to disable this feature.  Not the best way for a computer administrator to disable something.
