To support privilege separation, define the following environment variable

Using Pegasus Privilege Separation Functionality

before building.

PEGASUS_ENABLE_PRIVILEGE_SEPARATION

Privilege separation was added to Pegasus starting with Pegasus 2.7. This

is a security feature. It allows separation of the functionality so that

only a minimal set of code runs as a privileged user (ex. root) in a

separate process (the executor). The majority of pegasus runs as a

nonprivileged user (the cim server). The CIM Server makes requests on the

executor for functions that require root privilege.

cimserver is the executor program (see src/Executor)

The privilege separation functionality is documented in PEP 286.

cimservermain is the server program (see src/Server)

cimserver is the executor program (see src/Executor).

cimservermain is the server program (see src/Server and

src/Pegasus/Common/Executor.h).

Privilege separation is build-time optional functionality. To enable privilege

separation, define the following environment variable before compiling.

PEGASUS_ENABLE_PRIVILEGE_SEPARATION=true

If this build variable is not set, the cimserver runs as the user under which

it was started and all privelege separation functionality is disabled.

The nonprivileged user for privilege separation is the user under which the

cimservermain component executes. The name of this user is specified by the

PEGASUS_CIMSERVERMAIN_USER macro, whose default value is defined in

Constants.h. The specified user MUST exist or cimserver will terminate

immediately.
