I think, it would be nice to add the ability to customize the config CDS parameters such as UID_MIN, GID_MIN, I think not prevent such as UID_MAX, GID_MAX that the local nick not overlap with users from a directory
When done, add an entry in howto installation and moving to the CDS about these parameters, so as not to overlap with the /etc/login.defs, for example

1. grep -E '^[GU]ID_M(IN|AX)' /etc/login.defs
   UID_MIN 1000
   UID_MAX 1999
   GID_MIN 1000
   GID_MAX 1999

1. grep -E '^[GU]ID_M(IN|AX)' /etc/calculate/calculate.env
   UID_MIN = 2000
   UID_MAX = 10000
   GID_MIN = 2000
   GID_MAX = 10000
