(Accidentally pressed Enter)
This RSL will trigger the problem:

<job>
  <executable>/usr/bin/printenv</executable>
  <environment>
    <name>MYAPP_AUTHZ_SUBJECT</name>
    <value>CN=Olle Mulmo</value>
  </environment>
</job>

Output:
% globusrun-ws -submit -s -f x.rsl 2>&1 | grep AUTHZ
MYAPP_AUTHZ_SUBJECT=CN\=Olle Mulmo
% 

"CN=Olle Mulmo" is what gets transferred on the wire so the error is at the
server side. Not sure whether this is Fork adapter-specific problem or a
generic problem though.

Are there any other characters that will get escaped as well?

Reassigning to current GRAM developer to close/fix as appropriate.

Doing some bugzilla cleanup...  Resolving old GRAM3 and GRAM4 issues that are
no longer relevant since we've moved on to GRAM5.  Also, we're now tracking
issue in jira.  Any new issues should be added here:
