Documentation:
A mapping from BBDB to LDAP attributes.
This is a list of cons cells (BBDB-FIELD . SPEC-OR-LIST) where
BBDB-FIELD is the name of a field that must be defined in your BBDB
environment (standard field names are `name', `company', `net', `phone',
`address' and `notes'). SPEC-OR-LIST is either a single SPEC or a list
of SPECs. Lists of specs are valid only for the `phone' and `address'
BBDB fields. SPECs are sexps which are evaluated:
a string evaluates to itself,
a symbol evaluates to the symbol value. Symbols naming LDAP attributes
present in the record evaluate to the value of the field in the record,
a form is evaluated as a function. The argument list may contain LDAP
field names which eval to the corresponding values in the
record. The form evaluation should return something appropriate for
the particular BBDB-FIELD (see `bbdb-create-internal').
`eudc-bbdbify-phone' and `eudc-bbdbify-address' are provided as convenience
functions to parse phones and addresses.

You can customize this variable.
