[Samba] pdb_new_rid: Failed to find unused RID

[Dean Montgomery]

We are getting the following error trying to add new samba users or machines:

pdb_new_rid: Failed to find unused RID

Does this have something to do with idmap?

The following command shows a big jump in ID numbers with the last ones having 
the same number repeated.
pdbedit -L | awk -F: '{print $2 " " $1 ":" $3}' | sort -n
