Hi Arran. Thanks for your help.

You should only see the above entry with -C...

But it happens with "radiusd -X".

Modules which utilise a finite pool of connections to another server should not be loaded in config check mode, as instantiation may erroneously fail due to connection limits.

Confirm you saw that in the output of '-X' and not '-C'.

Confirmed.

...

(0) [files] = ok (0) ERROR: ldap_yyyyy : All ldap connections are in use (0) [ldap_yyyyy] = fail (0) } # authorize = fail

No, I cannot see any reason for that, and it works fine for me and others.

Please provide full debug, and confirm you experienced that issue on the first request.

Ug. sizeof(bool) != sizeof(int) on your system. Ok, pushed a fix, nothing to do with ldap. Check config global was being declared incorrectly in some files.

Thanks for the bug report.

I have tried the master git branch and now it works nicely :)

Thanks for confirming. I checked, and that's the last bool external. Globals are generally bad in a largish code base, but the problem gets much worse when declarations for them are sprinkled around multiple files. Interestingly non of the static analysis tools picked this up. Arran Cudbard-Bell <a.cudbardb@freeradius.org> FreeRADIUS Development Team FD31 3077 42EC 7FCD 32FE 5EE2 56CF 27F9 30A8 CAA2
