Full_Name: Dmitry Shupilov Version: 2.4.39 OS: RHEL 6.5 x86_64 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (86.57.254.70) Hello all! It's my first time to post here, so sorry if I will do something wrong :) I have to write shared library which task is to check if the user is correct LDAP user. First of all I prepare env and call ldap_initialize - nothing special here. The ldap_create function sets ld properly (e.g. ld = '0x7fffe40837d0') and in gdb I can read it by (p *ld) or even deeper (p *ld.ldc). But the next function cannot do its job - ldap_set_option failed with "-1" status. I tried to create separate binary which use my shared *.so to do the same job - check a user in LDAP and it works fine: ldap_create assigns "short" address (e.g. 0x602a30). In this case ldap_set_option do what it needs to do. My question is: is the problem of ldap_set_option in that "very long value of address" or is something else? How can I catch the reason of this problem and solve it? BR, Dmitry
