So the gosa+samba3.schema seems to make automatic conversion hickup
somehow. After commenting out the include-line for this schema,
conversion was successful, so something most be wrong with this
schema. I tried to figure out what could be wrong with this schema
myself, but i have no clue where i should start to look. At the moment
the slave-server is running without the gosa-things included (we don't
use them yet but sooner or later we'll include gosa) and it's working
perfectly. But as i need to get gosa working too, i need to know
what's wrong with the schema. I'll attach the schema to this email,
hopefully somebody can point me in the right direction.
