ZF-11639: Zend_Ldap casts all numeric fields to a float (including telephone numbers).
When using Zend_Ldap to access the telephoneNumber attribute, or in deed any similar attribute, by means of getAttribute(), it always casts the value to a float due to the value being numeric.
For example, if this was found within an LDAP entry: bq. +442012345678
The function: bq. $ldapNode->getAttribute("telephoneNumber", 0)
Would return: bq. 442012345678
The problem resides in: bq. Zend_Ldap_Converter::fromLdap() (line 221)
