+module: vertica_user
+version_added: '1.0'
+short_description: Adds or removes Vertica database users and assigns roles.
+description:
+  Adds or removes Vertica database user and, optionally, assigns roles.
+  A user will not be removed until all the dependencies have been dropped.
+  In such a situation, if the module tries to remove the user it
+  will fail and only remove roles granted to the user.
+options:
+  name:
+    description:
+      Name of the user to add or remove.
+    required: true
+    default: null
+  profile:
+    description:
+      Sets the user's profile.
+    required: false
+    default: null
+  resource_pool:
+    description:
+      Sets the user's resource pool.
+    required: false
+    default: null
+  password:
+    description:
+      The user's password encrypted by the MD5 algorithm.
+      The password must be generated with the format C("md5" + md5[password + username]),
+      resulting in a total of 35 characters. An easy way to do this is by querying
+      the Vertica database with select 'md5'||md5('<user_password><user_name>').
+    required: false
+    default: null
+  expired:
+    description:
+      Sets the user's password expiration.
+    required: false
+    default: null
+  ldap:
+    description:
+      Set to true if users are authenticated via LDAP.
+      The user will be created with password expired and set to I($ldap$).
+    required: false
+    default: null
+  roles:
+    description:
+      Comma separated list of roles to assign to the user.
+      [Alias I(role)]
+    required: false
+    default: null
+  state:
+    description:
+      Whether to create C(present), drop C(absent) or lock C(locked) a user.
+    required: false
+    choices: ['present', 'absent', 'locked']
+    default: present
+  db:
+    description:
+      Name of the Vertica database.
+    required: false
+    default: null
+  cluster:
+    description:
+      Name of the Vertica cluster.
+    required: false
+    default: localhost
+  port:
+    description:
+      Vertica cluster port to connect to.
+    required: false
+    default: 5433
+  login_user:
+    description:
+      The username used to authenticate with.
+    required: false
+    default: dbadmin
+  login_password:
+    description:
+      The password used to authenticate with.
+    required: false
+    default: null
+notes:
+  The default authentication assumes that you are either logging in as or sudo'ing
+  to the C(dbadmin) account on the host.
+  This module uses C(pyodbc), a Python ODBC database adapter. You must ensure
+  that C(unixODBC) and C(pyodbc) is installed on the host and properly configured.
+  Configuring C(unixODBC) for Vertica requires C(Driver = /opt/vertica/lib64/libverticaodbc.so)
+  to be added to the C(Vertica) section of either C(/etc/odbcinst.ini) or C($HOME/.odbcinst.ini)
+  and both C(ErrorMessagesPath = /opt/vertica/lib64) and C(DriverManagerEncoding = UTF-16)
+  to be added to the C(Driver) section of either C(/etc/vertica.ini) or C($HOME/.vertica.ini).
