Some of our users are experiencing an issue while accessing their gmail accounts while on our network. Our director says that he only receives this error at work and never while he's at home. The error says:

"Alert

An error occurred during a connection to www.google.com:443.

security library has experienced an input length error.

(Error code: sec_error_input_len)"

Any ideas on if this is a problem with out network and if so what it could be? Let me know what additional info you need. Thanks.

What browser(s) are your users using?

What is your network connection at the workplace?

How many users do you have? Is the connection saturated bandwidth-wise?

What's your firewall/UTM appliance, if any?

1.) At first I heard that the problem only happened in Firefox, but I've recently heard rumors of it happening in Safari as well.

2.) Not sure what you are looking for with this question? Are you wanting to know the speed coming into our building?

3.) We are a university, so the number of users is constantly fluctuating as students get on and off, but we have a little over a thousand students and maybe 200 faculty and staff.

4.) We have a Cisco ASA 5510 running our firewall.

Yep, speed of the pipe coming into your building and/or the organization as a whole is what I was curious about.
Do you have administrative control of the ASA?

hi

this problem mostly from your firewall ...

but if your O.Ss are Vista try this first
go to tools>options>advanced>encryption>*When a server requests for my personal certificate *choose "Select one automatically"

also try I.E6 or 7,,

if nothing solve the problem try accessing google outside your Firewall

Not sure on the network speed. I'm filling in on some of the network admins responsibilities as ours just left and we haven't hired a new one yet. I will ask around though as I'm sure that someone here knows, so I'll get back to you on that.

I do have administrative access to the ASA device.

I don't think it's a Vista issue as my boss (who has been having this issue as well) is running Snow Leopard. He never receives this error off campus though, only on campus. What should I check in the firewall to make sure that it's not a firewall issue?

Might be useful to see the rules/config of the ASA.
 Are the users able to connect to gmail, but receive the error after awhile? Or are do they never have success?

Users often get the error on the first attempt to connect with GMail.  It happens sporadically for some, most of the time for others.  It will let you pass through to GMail but when you read or compose, it will often pop up that annoying error box.

As far as the CSC goes, I'm not sure if it is running or not, but if it is, I wouldn't want to disable it.  Also, we made no changes to the firewall and this just started happening.

It has happened on multiple browsers, especially Firefox, but also Safari.  It seems to have stopped now, again with no intervention on our part.  Any ideas on what happened or what we can do to prevent it would be appreciated.
