RFC 7644 §3.4.2.4 specifies that out-of-range pagination values MUST be
clamped, not rejected. The previous implementation used FastAPI Query
constraints (ge=1, le=100) which caused a 422 response for values like
startIndex=0 or count=9999 — violating the spec.
For both /Users and /Groups:
- startIndex < 1 is now treated as 1 (spec: "SHALL be interpreted as 1")
- count < 0 is now treated as 0 (spec: "SHALL be interpreted as 0")
- count > 100 is clamped to the server maximum of 100
