-This test code requires a tdb that is configured for to use the asq module.
-You can do that adding the following record to a tdb:
-
-dn: @MODULES
-@LIST: asq
-
-Other modules can be used as well (like rdn_name for example)
-
-The uidNumber 0 and the gidNumber 0 are considered invalid.
-
-The user records should contain the followin attributes:
-uid (required) the user name
-userPassword (optional) the user password (if not present "LDB" is
- returned in the password field)
-uidNumber (required) the user uid
-gidNumber (required) the user primary gid
-gecos (optional) the GECOS
-homeDirectory (required) the home directory
-loginShell (required) the login shell
-memberOf (required) all the groups the user is member of should
- be reported here using their DNs. The
- primary group as well.
-
-The group accounts should contain the following attributes:
-cn (required) the group name
-uesrPassword (optional) the group password (if not present "LDB" is
- returned in the password field)
-gidNumber (required) the group gid
-member (optional) the DNs of the member users, also the ones
- that have this group as primary
