libldap.so: undefined reference to `RAND_egd'

RAND_egd does not exist because OpenSSL was built with the default settings

which, as of 1.1, has "EGD" disabled by default [0].

[0] 0423f812dc Add a no-egd option to disable EGD-related code

  *) EGD is no longer supported by default; use enable-egd when
     configuring.
     [Ben Kaduv and Rich Salz]

The RAND_egd reference is in libraries/libldap/tls_o.c:
