Bug#991545: gosa: gen_uids() function not producing expected results

[Mike Gabriel]

Package: src:gosa
Severity: important
Version: 2.7.4+reloaded3-8+deb10u2
Tags: patch

While mass creating users these days for a school customer, I noticed  
that an idGenerator expression such as "{%sn[6-8]}{%givenName[2-4]}"  
does not produce expected results if many UIDs have already been taken.

In my case (making up names here), I had

   sn: Fresher
   givenName: Jim

The following login name was already in use:

   fresheji

So, the expected results for gen_uids() would have been:

   fresherji
   freshejim
   fresherjim

But gen_uids() returned an empty result array().

This is caused by an off-by-one string element check in gen_uids().

Patch attached.

Mike
