Description of problem:
When the organisation name contains special characters, e.g. 'Example, Inc.' it causes cobbler to fail upon creating a kickstart file.

When Cobbler creates the kickstart name, e.g. 1:servers:Red-Hat, it replaces spaces with '-', yet it doesn't seem to be able to manage special characters such as ',' and '.'. If this is the case then customers/users should not be able to input these into the organisation name, they should also never appear in Satellite Certificates.

Version-Release number of selected component (if applicable):
RHN Satellite 5.3.0 Embedded-Database
RHEL 5.4

How reproducible:
Every time for me on RHN Satellite 5.3.0. 

Steps to Reproduce:
1. Create an Organisation with a name that contains special characters, e.g. ','
2. Login as an Organisation Admin or a user that can create kickstarts
3. Attempt to create a kickstart file for this organisation
  
Actual results:
'Internal Server Error'
The server is unable to create the kickstart file, there's no evidence of anything in the Satellite UI, it's not partially created at all. 

Expected results:
Kickstart created based on the organisation, either Satellite or Cobbler needs to be able to parse organisation names with special characters or not allow them to be entered at all. 

Additional info:
If the organisation is renamed (even with software/configuration channels assigned) to one without the special characters, e.g. from our previous example 'Example Inc', kickstarts are able to be made straight away.

Log files do show that there's an error in the name (/var/log/tomcat5/catalina.out)
