Update the proxyaddresses attribute via rsldapsync_user

Question

Dear Gurus,
i configured a ldap-scenario and tested it by reading different attributes from the directory and updating the user information.
It worked well!
Now i want to write the proxyaddresses-attribute into the directory. i configured an exporting mapping from the e-mail address of the sap-user to the mentioned dir.-attr.. In this mapping i call a function module. For simple testing i call an ldap-module to read the actual values of the directory-attribute and write them back to the directory:
  Read table attributes with Key var = 'USERNAME' fld = 'BAPIBNAME' assigning <hybral>.
  READ TABLE <hybral>-vals index 1 ASSIGNING <vals>.
  CONCATENATE '(&(objectclass=user)(samaccountname=' <vals>-val '))' into filter.
  CALL FUNCTION 'LDAP_READ'
     EXPORTING
*   BASE                = ''
     base_string         = 'ou=test-ou,dc=test-domain1,dc=test-domain2'
     scope               = 2
     filter              = filter
*   FILTER_STRING       =
*   TIMEOUT             =
     attributes          = it_attr
     IMPORTING
       ldaprc              = ldaprc
       entries             = ldapetab
     EXCEPTIONS
       no_authoriz         = 1
       conn_outdate        = 2
       ldap_failure        = 3
       not_alive           = 4
       other_error         = 5
       OTHERS              = 6
  READ TABLE ldapetab INDEX 1 ASSIGNING <ldape>.
  READ TABLE <ldape>-attributes WITH KEY name = 'PROXYADDRESSES' INTO ls_attribute_ldap.
  ls_attribute_ldap-typ = 'C'.
  INSERT ls_attribute_ldap INTO TABLE attributes_ldap.
at the end of the module i export the values into attributes_ldap. When i debug the folowing steps, the values are cummincated throughout the ldap-function-modules that are used by rsldapsync_user. The ldap_modify module exports a returncode 53.
Now i want to know if it is possible to update the proxyaddresses-attribute in this manner. Are there any mistakes in my thinking or in the posted function-module. Does anyone of you have some experience updating multiple line entries in Active Directory via SAP-LDAP?
Thanks in advance

Now i wrote a function module which reads an attribute and tries to write it back to the active directory.

After LDAP_READ the ldaprc = 0.
After LDAP_READ ldaprc is 53.
So i can exclude a wrong mapping in transaction ldap.
