Hello, Francesco,

I created two files manually:
*cat /usr/lib64/pkgconfig/ldap.pc*
prefix=/usr
exec_prefix=/usr
includedir=/usr/include
libdir=/usr/lib64

Name: ldap (OpenLDAP)
Description: OpenLDAP Lightweight Directory Access Protocol library
URL: https://www.openldap.org
Version: 2.4.46
Requires: lber
Cflags: -I${includedir}
Libs: -L${libdir} -lldap
Libs.private: -levent  -lsasl2 -lssl -lcrypto


*cat /usr/lib64/pkgconfig/lber.pc*
prefix=/usr
exec_prefix=/usr
includedir=/usr/include
libdir=/usr/lib64

Name: lber (OpenLDAP)
Description: OpenLDAP Lightweight ASN.1 Basic Encoding Rules library
URL: https://www.openldap.org
Version: 2.4.46
Cflags: -I${includedir}
Libs: -L${libdir} -llber
Libs.private: -levent


Now the configure script works well.

Thank you for the help.

Kind regards,
      Ankor.
