You can modify diverse parameters of an existing role, including its privileges.
Modify a role's description:
config:#
role modify <name> description "<description>"
Variables:
<name> is a string comprising up to 32 ASCII printable characters.
<description> is a description comprising alphanumeric characters. The <description> variable must be enclosed in quotes when it contains spaces.
Add more privileges to a specific role:
config:#
role modify <name> addPrivileges <privilege1>;<privilege2>;<privilege3>...
If a specific privilege contains any arguments, add a colon and the argument(s) after that privilege.
config:#
role modify <name> addPrivileges <privilege1>:<argument1>,<argument2>...; <privilege2>:<argument1>,<argument2>...; <privilege3>:<argument1>,<argument2>...; ...
Variables:
<name> is a string comprising up to 32 ASCII printable characters.
<privilege1>, <privilege2>, <privilege3> and the like are names of the privileges assigned to the role. Separate each privilege with a semi-colon. See All Privileges.
<argument1>, <argument2> and the like are arguments set for a particular privilege. Separate a privilege and its argument(s) with a colon, and separate arguments with a comma if there are more than one argument for a privilege.
Remove specific privileges from a role:
config:#
role modify <name> removePrivileges <privilege1>;<privilege2>;<privilege3>...
If a specific privilege contains any arguments, add a colon and the argument(s) after that privilege.
config:#
role modify <name> removePrivileges <privilege1>:<argument1>,<argument2>...; <privilege2>:<argument1>,<argument2>...; <privilege3>:<argument1>,<argument2>...; ...
Note: When removing privileges from a role, make sure the specified privileges and arguments (if any) exactly match those assigned to the role. Otherwise, the command fails to remove specified privileges that are not available.
