+short_description: Configure FlashBlade  Management Directory Service Roles
+description:
+- Set or erase directory services role configurations.

+options:
+  state:
+    description:
+    - Create or delete directory service role
+    default: present
+    choices: [ absent, present ]
+  role:
+    description:
+    - The directory service role to work on
+    choices: [ array_admin, ops_admin, readonly, storage_admin ]
+  group_base:
+    description:
+    - Specifies where the configured group is located in the directory
+      tree. This field consists of Organizational Units (OUs) that combine
+      with the base DN attribute and the configured group CNs to complete
+      the full Distinguished Name of the groups. The group base should
+      specify OU= for each OU and multiple OUs should be separated by commas.
+      The order of OUs is important and should get larger in scope from left
+      to right.
+    - Each OU should not exceed 64 characters in length.
+  group:
+    description:
+    - Sets the common Name (CN) of the configured directory service group
+      containing users for the FlashBlade. This name should be just the
+      Common Name of the group without the CN= specifier.
+    - Common Names should not exceed 64 characters in length.
