+# To keep track of formerly used UIDs/GIDs, they are always also added to
+# uid/gid allocation tables. Rows in these tables are never deleted.
+# User/group tables have foreign key constraints to ensure that there can
+# only ever be three cases for a given ID:
+#
+# 1. The ID was never used (does not exist in either user/group or allocation

+# 2. The ID was used, but the user/group was deleted (it does not exist in
+#    user/group table, but it exists in the allocation table)
+# 3. The ID is in use (it exists in both the user/group and the allocation
+#    table)
+#
+# For auto-allocation, there are a few edge cases to consider:
+#
+# 1. GIDs can be chosen freely in the web interface, e.g. one could easily
+#    create a group with the last GID in range.
+# 2. For UIDs there are two ranges (for regular users and for service users).
+#    The ranges may either be the same or they may be different but
+#    non-overlapping.
+# 3. ID ranges can be changed (e.g. extended to either side if the old range
+#    is exhausted). Existing IDs should not change.
+#
+# The approach we use here is to always auto-allocate the first unused id
+# in range. This approach handles the three edge cases well and even behaves
