Subject: [PATCH] openldap: replace ldap_ prefix on private functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Since openldap itself uses that prefix and with OpenĹDAP 2.5.4 (at
least) there's a symbol collision because of that.
The private functions now use the 'oldap_' prefix where it previously
used 'ldap_'.
Reported-by: 3eka on github
Fixes #7004
Closes #7005
