Guessing here: You are and have been running the same exact code for a number 
of years. So my bet would be that something else changed external to CAS, or is 
acting up somehow, recently. I’d look into your LDAP/CAS logs for the times the 
attribute is not being released and trace the activity. Also you should narrow 
down the scope. Is that the only attribute that is not received? Do all fail to 
be released? Does it fail for a particular user id? What values are there for 
the failing case? What does your management app use for storage? Etc. The fewer 
variables, the better.

Subject:  [cas-user] CAS 3.5.3 Intermittent Attribute Issues  

Hi,

We originally set up CAS server 3.5.3 as a development server before 4 was 
released and we have been running version 3.x for 1-2 years without any issue.

However, recently this server started to have an issue with one of the 
attributes that is released.

Here are some specifications:
We are reading the employeeId attribute and using LDAP for authentication.
The service authorization has been setup to release one or more attributes to 
all of the web apps that are developed in a particular location on a 
development server.
CAS and web app servers are using Tomcat 6
The attribute mentioned above recently began to not show up sometimes in the 
CAS response, even though the user account does have the attribute set in AD.

Some things we have tried to resolve this each time it happens include:
Update the service definition in the CAS Service Management web app to not 
release the attribute and then update it again to release it.
This seems to work sometimes, but not always.
Clear the browser cache and then access the web app again
This also does not work every time.

Any suggestions would be extremely appreciated!

Thanks,
Matt
