[mwatson-delphix]

** Expected Behavior**
operation should be successful.

Note: provision via the GUI is successful without error, with this configuration.

** Actual Behavior**

Various commands fail with errors if the user does not have at least read permission on the namespace(s).

Steps To Reproduce the Problem

• Replicate dsource from Engine A -> B
• Create environment on target to provision to
• Create limited permissions user on target

( G1 = Group name )

mwdlpx-dxtest-20-repl.dcol2 authorization> list user=u1
REFERENCE         USER  ROLE         TARGET
AUTHORIZATION-7   u1    OWNER        u1
AUTHORIZATION-8   u1    OWNER        G1@mwdlpx-dxtest-20.dcol2-1
AUTHORIZATION-9   u1    PROVISIONER  G1@mwdlpx-dxtest-20.dcol2-1
AUTHORIZATION-10  u1    Read         G1@mwdlpx-dxtest-20.dcol2-1
AUTHORIZATION-11  u1    Data         G1@mwdlpx-dxtest-20.dcol2-1
AUTHORIZATION-15  u1    Data         Untitled
AUTHORIZATION-16  u1    PROVISIONER  Untitled

Note specifically, the missing permission is Read on the mwdlpx-dxtest-20.dcol2-1 namespace.

• Provision using dxtoolkit, which will now fail with various "uninitialized value" depending on the exact command.

• Workaround

Add read permissions on the namespace resolves the issue,

mwdlpx-dxtest-20-repl.dcol2 authorization> create
mwdlpx-dxtest-20-repl.dcol2 authorization create *> set target=Namespace:/mwdlpx-dxtest-20.dcol2-1
mwdlpx-dxtest-20-repl.dcol2 authorization create *> set user=u1
mwdlpx-dxtest-20-repl.dcol2 authorization create *> set role=Read
mwdlpx-dxtest-20-repl.dcol2 authorization create *> commit

**Version**

* Delphix - 20
* dxtoolkit - 2.4.22
