7    ldap2model.pl - convert LDAP schema file into Jifty model
8    
9    =head1 DESCRIPTION
10    
11    Create model from ldif data
12    
13      ./bin/ldap2model.pl --model hrEduOrg --path data/all.ldif
14    
15    or directly from LDAP server
16    
17      ./bin/ldap2model.pl --model inetOrgPerson
18      ./bin/ldap2model.pl --model organization
19    
20    which must match C<LDAP.objectClass> in C<etc/conf.yml>
21    
22    With C<--debug> switch all output will go to C<STDOUT>
23    instead to files.
24    
25    If your schema for model doesn't include some objectClasses
26    and you want to mixin them manually, use something like:
27    
28      ./bin/ldap2model.pl --model hrEduOrg --mixin dcObject --mixin posixAccount
