1. Cimservermain must be owned by ordinary user. For example:

1. The user that runs cimervermain is determined as follows.

% chown pegasus.pegasus cimservermain

(1) Look for serverUser configuration option on command line.

Cimservermain runs as this user.

(2) Look for serverUser configuration option in planned configuration

file.

2. Cimservermain must be able to create files directly under $PEGASUS_HOME.

(3) Use the owner of the cimservermain program (if not root).

For example, it must create the cimserver.password file.

(4) Use "pegasus" (the default user).

We solved this by having the executor access those files.

2. All files but the repository are owned by root. The cimservermain

process may read any of the root owned files, but it must ask the

executor to modify the file system.

3. Cimservermain must own $PEGASUS_HOME/repository and all files beneath.

3. Cimservermain must own the repository and all files beneath.

The executor automatically sets ownership for these files upon

startup.

For now, the executor automatically sets ownership for these files.

4. Provider agent is run as root, whenever the same user as server is

requested.

providers with privilege.

For now, we use the same user as the executor.

7. Cimservermain owns the local-domain socket file (/tmp/cimxml.socket).

5. Executor now checks whether Pegasus repository exists and errors out

if not. Is this okay?

6. The configuration file has a repositoryDir key. What is that for and

does it mean that the executor cannot reliably locate the repository

with the constant in Constants.h?

7. Cimservermain owns the local-domain socket file.

8. For logging purposes, the executor uses "cimexecutor" as its syslog

identifier.
