SCIM Parser disregards grouping with parenthesis

[suraj-2584]

Setup:

• I am using SimpleIdServer.Scim.Parser.SCIMFilterParser to parse filter strings into a SCIM Expression tree.
• using SimpleIdServer.Scim.Parser
• var filter = ( username eq 'suraj' ) and (( id eq 123 ) or ( id eq 456 ))
• SCIMFilterParser.Parse(filter)

Expected:

• ( id eq 123 ) or ( id eq 456 ) will be evaluated first, followed by a AND with ( username eq 'suraj' )
• SCIM Expression tree :

            AND
           /    \
  userName eq    OR
    'Suraj'     /    \
            id eq   id eq
             123     456

Actual:

• ( username eq 'suraj' ) and ( id eq 123 ) is evaluated first followed by a OR with ( id eq 456 )

• Resulting SCIM Expression tree :

              OR
            /    \
        AND       id eq
       /    \       456
username eq  id eq
   'Suraj'     123

Indeed, there is an issue with the parsing.
The issue has been fixed in the branch release/v6.0.4.

Kind regards,
