Intermittent LDAP authentication failures – Wednsday, Oct. 26, 2011 3:50 PM

Posted on October 26, 2011 by Casey Carvalho

One of the various load balanced, front end LDAP servers used for service authentication stopped processing authentication requests. This would have been perceived by some users as an intermittent login failure to some applications. Some web based applications that require authentication may have been affected. Blackboard and other critical applications were not affected.

The proxy LDAP server was restarted around 3:50 PM today, and the problem was resolved.

We apologize for the service disruption.

my.ryerson.ca login problem resolved

Posted on October 24, 2011 by Brian Lesser

The Central Authentication System (CAS) that allows you to log into my.ryerson.ca and other systems was brought back online at approximately 8 PM. The problem with the devices that provide encryption (SSL) services for CAS was resolved by reconfiguring the devices. The work also required reissuing SSL certificates.

Please accept our apologies for the problems the outage caused.

Can’t Log in to my.ryerson.ca and other systems

Posted on October 24, 2011 by Brian Lesser

The Central Authentication System (CAS) that allows you to log into my.ryerson.ca and other systems is offline due to a hardware problem. The problem is with the device that provides encryption (SSL) services for CAS.  The problem is related to the earlier problem with Webmail and began some time after the Webmail problem was resolved at 4:15.

CCS support staff are working to reconfigure the device.

Update at 7 PM: reconfiguring the SSL accelerator is slow painstaking work. We still don’t have an estimated time to resolve the problem.

Update at 8 PM: We believe the problem is resolved. 

Please accept our apologies for the problems this outage is causing.

Peoplesoft applications & Internet Explorer 7 drop-down menu issues – Friday, Oct. 14, 2011

Posted on October 14, 2011 by Casey Carvalho

We suspect that a recent Microsoft Windows update may have introduced some issues with drop-down fields in PeopleSoft applications, when invoked via my.ryerson (e.g.: eHR, SAS, OGF). The problem seems to be specific to Internet Explorer 7.

We are still investigating, but upgrading to Internet Explorer 8 (http://windows.microsoft.com/en-CA/internet-explorer/products/ie/home) appears to remedy the problem.

Mail delays due to spam – Wedn., Oct. 12, 2011 11:30 PM – Thu., Oct 13, 2011 10:00 AM

Posted on October 13, 2011 by Casey Carvalho

A compromised account started sending out spam overnight, causing delays in e-mail delivery starting around 11:30 PM last night and lasting until this morning around 10 AM.
Due to issues with  Blackberry e-mail delivery notifications, on-call staff did not get alerts to the problem last night and only received the notification around 6 AM.
CCS started responding to the problem shortly after 6AM and by 10AM the problem has been cleared.
One website seems to have blocked us (comcast.net). We are investigating this and will take necessary measures to correct the problem.

We apologize for the service disruption.

Posted on October 11, 2011 by

At approximately 11:00 am users noticed that their Sophos Anti-Virus signatures were not being updated. It was determined that the Sophos update server had run out of disk space and was unable to get new signatures,(dat files).
The disk space was increased, the update folders were refreshed and the updates were re-run.
At approximately 3:00 pm the problem was resolved and the Sophos Anti-Virus software updates was functioning normally.

We apologize for the inconvenience,
