I have a situation where I need to support more than 1024 categories

error message.  Do I need to restart any of the services?

Here is the command that was run and the output after applying the
patch below:

ipa config-mod
ipa: ERROR: invalid 'ipaselinuxusermaporder': SELinux user
'staff_u:s0-s15:c0.c16383' is not valid: Invalid MCS value, must
match c[0-1023].c[0-1023] and/or c[0-1023]-c[0-c0123]

Have you updated your SELinux policy to support a larger MCS range? If
not then this will get you past the IPA validator but it won't work
with SELinux. See semanage(8).


Yes.  I’m trying to set the SELinux categories in freeipa because when
you have lots of categories all semanage commands slow down (way down).
  For other people’s knowledge, this requires recompilation of the
SELinux policy.

Ok, then your patch looks reasonable. The current code is for the default values and we haven't had cause to make this configurable before now. You might consider filing a ticket in our trac about this.

Also note that this change will be lost on your next IPA upgrade, and you'll need to make this change on any IPA master you want these values to be managed. The data will remain unchanged, but the original python values will be restored if you update the packages.

I don't believe validators are currently extensible in the IPA framework. That might be something we need to look at as well.
