Hello Alan and all,

unfortunately I bumped into a side issue when trying to test this. My
dev system is old, CentOS 6.10

[root at devradius ~]# gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-23)

Building branch 3.0.x fails with the following error:

Is there a way to overcome this (without upgrading gcc)?
I think this will be an issue affecting 3.0.18 release. Would you like
me to report it in a github issue?

Tomorrow I will test in a newer CentOS 7 system to test the actual ldap
module fix.
