ldap -llber lost

Change in revision 1.232 of `configure.in' caused lossage in the following circumstances. . System ldap applications must be linked with `-lldap -llber'. Linking with `-lldap' only causes undefined symbol errors. . `--with-ldap' arg was specified to `configure'. In this case `configure' fails to detect library that must be linked to use ldap. `with_ldap' is `yes', and appropriate `AC_CHECK_LIB' is not called. `with_ldap_lber' left unset, and `ldap_libs' are not set properly. This breaks further check of ldap toolkit features and `eldap.c' compilation. Never checked other ldap toolkits with other sets of required libraries. Please decide what should mean that `--with-ldap' was specified by `configure' caller and what should mean success of some stage of ldap toolkit auto-detection, and fix the confusion.
