Description of problem: 
Looking at the sources for the "libuser" library, I'm guessing the LDAP backend is 
incomplete. I've been trying to use the "libuser" LDAP backend to manage my user 
and group accouns that I've stored in my OpenLDAP server. What I found is that I 
can't use "lgroupadd" to add a group using the LDAP backend. 
 
Looking at the sources, the "lgroupadd" command-line tool invokes the 
"lu_ldap_group_add" located in "modules/ldap.c". This function, in turn, will invoke 
"lu_ldap_set" which is able to perform modifications, but not additions to the 
OpenLDAP directory. 
 
The problem here is that invoking "lgroupadd" to add a new group "testgroup", will 
map the group "testgroup" to an LDAP distinguised name of "cn=testgroup, 
ou=groups, dc=example, dc=com" (for example). Note that we are trying to add a 
new directory entry. However, the "lu_ldap_set" function will try to perform a 
modification (LDAP_MOD) and since the entry doesn't exist in the directory, it will 
fail. 
 
The "libuser" LDAP module backend is thus incomplete, and unable to properly 
manage additions, like adding groups and users to the directory. 
 
Version-Release number of selected component (if applicable): 
libuser-0.51.7 
 
How reproducible: 
Always 
 
Steps to Reproduce: 
1. Install libuser-0.51.7 
2. Modify "/etc/libuser.conf": 
... 
modules = ldap 
create_modules = ldap 
... 
[ldap] 
server = your.server.name 
basedn = dc=example,dc=com 
... 
 
3. Invoke "lgroupadd testgroup". It will complain that the group can't be added. 
This was expected, since the LDAP backend module is trying to perform a 
modification on the group, which doesn't exist, as we are trying to add it. 
     
Actual results: 
libuser's LDAP backend is completely useless. 
 
Expected results: 
libuser's LDAP backend should be able to properly perform add operations on an 
LDAP directory. 
 
Additional info: 
Will this get fixed? We're implemented a centralized OpenLDAP directory for user 
authentication and we miss a tool that allows to add users/groups to the directory. 
We though "libuser" was the solution, but it seems incomplete.
