Before you can migrate your users, the target repository must be extended to support the Enterprise Server configuration objects. How you do this will vary slightly depending on the particular LDAP server that you are using. In all cases, you will create use the MFDS -L command to create an LDIF file containing the necessary extensions and then use the relevant import command for your LDAP server.
The Monitor and Control users are defined in Sign On Table (SNT) entries. These are stored in a file called dfhdrdat. By default this is stored in %ProgramFiles(x86)%\Micro Focus\Enterprise Developer\etc\cas (Windows) or $COBDIR/etc/cas (UNIX). This has an associated index file, dfhdrdat.idx. Both files must be in the same location. If dfhdrdat.idx doesn't exist, it is created the first time dfhdrdat is accessed.
cas-to-ad
cas-to-ad -u myuser -p password -r . -l localhost:389
This extracts user definitions from dfhdrdat and attempt to import them into your LDAP Directory.
