The ldap.conf SASL_NOCANON configuration option (or LDAPSASL_NOCANON environment
variable) should set the default behaviour for OpenLDAP tools such as
ldapwhoami. This configuration option should allow users to use the tools
without having to use the matching command line option (-N). Unfortunately, the
current code sets the option to true/false after only querying the command line
I'm linking to a patch that looks at the current value of the option first, and
if it's true, skips processing the command line option (which would either be a
redundant -N keeping the option true, or an absence of -N which implies the user
wants to use the configured value (true)).
Another approach would be to set the initial value of nocanon to UNINITIALIZED
(-1?). Command line arguments could set nocanon to 1 (true, -N) or false (0,
--canon?). Then we would only call ldap_set_option if nocanon was not
I can work up a patch using this second approach if people prefer. If so, let
me know if you want me to define UNINITIALIZED, or to just use -1.
I didn't check, but I would not be surprised if this same clobbering occurred
for other command line options.
