# Configure User Security

Knowledge Discovery user security provides user authentication, and checks which security privileges users have in third-party repositories. This includes the retrieval of group information from OmniGroupServer.

TIP: The Community component manages a database of users. You can populate this database manually, or configure Community to populate the database from a third-party directory. For more information about users in Knowledge Discovery, refer to the Community Component Help.

To configure user security

1. Open the Community component configuration file.

2. In the `[Server]` section, set the following parameter.

   `DeferLogin` | To automatically add users to Community the first time they log on to a front end, set `DeferLogin=True`. Community is populated with user information from your configured security repositories, for example your LDAP directory. If you want to add users to Community manually, set `DeferLogin=False` and add users with the `UserAdd` action. For more information about adding users manually, refer to the Community component Help.

3. In the `[Security]` section, list the security types that you want to configure. Start numbering from 0 (zero), for example:

       [Security]
       0=NT
       1=LDAP
       2=Notes

4. In the `[Security]` section, set the following parameters.

   `SecurityInfoKeys` | The path of your AES key file. This is used to encrypt and decrypt the security strings that Knowledge Discovery generates for each user. For this reason, the value of `SecurityInfoKeys` must be the same for each component that requires it (for example, Content, Community, and DAH must all use the same key file). If you need to generate a new key file, use the `autpassword` utility. Generate a key file in the same way as for encrypting passwords. For more information about using the `autpassword` utility, see Encrypt Passwords.
   `CheckEntitlement` | To authenticate users before returning a `securityinfo` string, set this parameter to `true`. Be aware that the default value of this parameter is `false`, which means that a `securityinfo` string can be obtained without authentication.
   `DefaultSecurityType` | An integer that specifies the security repository to use to authenticate users when the `Repository` action parameter is not set in the `Security` or `UserRead` action. Using the values from the example above, you would set `DefaultSecurityType=0` for NT authentication and `DefaultSecurityType=2` for Notes authentication.
   `SyncRolesFromGroups` | Set this parameter to `true` to synchronize roles from NT groups. This ensures that a user's permissions and NT groups are always in sync. The default value for this parameter is `false`.
   `GroupServerParentRole` | If you set `SyncRolesFromGroups` to `true`, `GroupServerParentRole` allows you to specify the parent role to which Community adds new roles that it creates. If you don’t specify a parent role with `GroupServerParentRole`, Community adds the new roles that it creates to the top role in the hierarchy.

   For more information about the configuration parameters that you can use, refer to the Community component Help.

5. Create a section for each of the security types that you listed. For example:

       [NT]
       CaseSensitiveUserNames=FALSE
       CaseSensitiveGroupNames=FALSE
       Library=./modules/user_ntsecurity
       DocumentSecurity=TRUE
       DocumentSecurityType=NT_V4
       v4=true
       SecurityFieldsCSVs=username,domain
       GroupServerHost=123.45.6.7
       GroupServerPort=3057
       Domain=Autonomy

       [LDAP]
       Library=./modules/user_ldapsecurity
       DocumentSecurity=FALSE
       LDAPServer=ldap
       LDAPPort=389
       RDNAttribute=uid
       Group=o=Company,ou=Users
       ...

       [Notes]
       ...

   The parameters in each section depend on the type of repository. You can set the following parameters:

   Parameter | Description
   --- | ---
   `Domain` | (NT security only) If you are configuring NT security, specify the name of the NT domain to use.
   `Library` | The path of the library to use to authenticate users. The authentication libraries that OpenText currently supplies are: `user_autnsecurity`. Autonomy authentication. `user_ntsecurity`. NT authentication. `user_notessecurity`. Lotus Notes authentication. `user_ldapsecurity`. LDAP authentication. Specify the library you want to use without the file extension.
   `v4` | Set this parameter to `true` if the security section defines security for NT or Exchange data and you are using a version 4 security type.
   `GroupServerHost` | The IP address of the machine on which your group server is located.
   `GroupServerPort` | The ACI port of the group server.
   `GroupServerParameters` | One or more parameters to send to the group server in addition to `username`. Separate multiple parameters with a comma (there must be no space before or after a comma).
   `GroupServerPrefixDomain` | Set this parameter to `true` to prefix domain information to the user name when contacting the group server, so that you can handle users in different domains who have the same user name.
   `GroupServerUserField` | The field that Community must read the user name from. Use this parameter in cases where the group server contains multiple user name fields (for example, a field that contains the full name and another field that contains a shortened name).
   `CaseSensitiveUsernames` | A Boolean value that specifies whether user names for this security type are case sensitive. If you set this parameter to `false`, Community returns upper case user names.
   `CaseSensitiveGroupNames` | A Boolean value that specifies whether group names for this security type are case-sensitive. If you set this parameter to `false`, Community returns upper case group names.
   `DocumentSecurity` | Set `DocumentSecurity` to `True` if this user security repository corresponds to a document security module that you configured in the `[Security]` section of your Content component configuration file. The Community component uses this information to generate an appropriate security string for the users in this repository. If you set this parameter to `TRUE` you must also specify the name of the security module with the `DocumentSecurityType` parameter. Otherwise, set this parameter to `false` (for example, to use `LDAP` or `autonomy` security).
   `DocumentSecurityType` | (If you have set `DocumentSecurity` to `true`). The name of the corresponding security module, as listed in the `[Security]` section of the Content component configuration file.
   `SecurityFieldCSVs` | Specify one or more security fields needed for the security type. All the fields you specify with `SecurityFieldCSVs` must be listed in the `[SecurityFields]` section. Separate multiple values with a comma (there must be no space before or after a comma). For more information on required fields for your security types, see SecurityInfo Parameters.

6. Save and close the configuration file.
