Another thing i would like to ask so as to be more sufficient on what i have accomplished
can you tell me please looking on my logs after using the commands:

1)ldapsearch -Y GSSAPI  -D "cn=M@nSpi,dc=teipir,dc=gr" -b "cn=bla bla bla...,ou=Managers,dc=teipir,dc=gr" -W -d 5


and i face a problem with the uid attribute as you can see on the log seems to be empty...

hope is not cause i havent added the  

rootdn          "cn=admin,dc=olp,dc=net"

authz-regexp

 "gidNumber=0\\\+uidNumber=0,cn=peercred,cn=external,cn=auth"
 cn=admin,dc=olp,dc=net

as Dan mentioned (so as not to have the error: No preauth found, returning PREAUTH-REQUIRED )





2)and this is the one i get when i login via php 


Thank you!!
