mldap_search output error

Hello, i'm using Vugen 12.52, and i try to create new script for testing several technology. This time i would like to check my LDAP querying it and compare the result to a known value to confirm that LDAP is working preperly.

here is my code:

// Search entry Dupont

mldap_search ("LDAP Search OpenLDAP",

"Base=dc=eforpro,dc=fr", "Scope=Base",

"Filter=(name=DUPONT)",

"Timeout=10", "Mode=ASYNC",

"SaveAsParam=True",

"Attrs=uid,mail",

LAST );

lr_output_message ("The uid value is: %d", lr_eval_string("{mldap_attribute_uid_0}"));

lr_output_message("The mail value is: %s", lr_eval_string("{mldap_attribute_mail_1}")); 

Here the output:

Action.c(24): The uid value is: 109972000

Action.c(25): The mail value is: {mldap_attribute_mail_1} 

I test with LDAPAdmin and it works, now i do not understand why line 25 return the variable name and not his value, in the meantime (as i'm not an expert of C), i do not understand the corresponding of the umerical value retrieve by the script. I would like to compare this value with one entry in my LDAP.

Thx for your help
