Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

+++ This bug was initially created as a clone of Bug #1097868 +++
The LDAPJDK utilizes the following Java calls which honor 'i18n':
* toLowerCase()
* toUpperCase()
These honor 'i18n' because they are actually calling the following:
* toLowerCase(Locale.getDefault())
* toUpperCase(Locale.getDefault())
This can cause problems for certain locales.
For example, if the default Locale is 'Turkish' (tr), the following problems arise when toLowerCase() is utilized:
* uppercase non-dotted 'I' is translated to lowercase non-dotted 'i'
* uppercase dotted 'I' is translated to lowercase dotted 'i'
Similar issues may exist for other Locales, including issues such as multibyte character sequences as supported by 'UTF-8'.
This bug proposes that te LDAPJDK be changed to no longer honor 'i18n' for attribute types, but still honor 'i18n' for all attribute data values:
* toLowerCase() --> toLowerCase(Locale.ENGLISH)
* toUpperCase() --> toUpperCase(Locale.ENGLISH)
Obviously, each individual usage of these two commands must be reviewed carefully to make certain that they are only being used on attribute names and not attribute data values.

This is a good catch. In fact if an attribute name contains a 'i' there is a chance the string manipulation in ldapjdk will translate 'i' into a dotless 'i' if we are in tr_TR.UTF8.
Will try to reproduce.
A workaround would be to set LANG=C

I have been unable to reproduce (mozilla/directory/java-sdk/tools/LDAPSearch.java).
run the command with LANG="tr_TR.utf8" and doing some searches like LDAPSearch -h localhost -p 1389 -D "cn=directory manager" -w Secret123 -b "dc=com" -S descrIptIon "descrIptIon=*" descrIptIon.
However, it is likely that use of toLowerCase/toUpperCase creates an issue but I was not able to do a test case
