HTTPD service is failed due to mod_ldap.so

Hi friends,

I have an issue related to Apache HTTPD service, which failed and thrown an exception as show below


Starting httpd: httpd: Syntax error on line 161 of /etc/httpd/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_ldap.so into server: /etc/httpd/modules/mod_ldap.so: undefined symbol: apr_ldap_ssl_init [FAILED]

This was working fine before one of our software got updated, which in-turn updated its dependencies such as libapr-1.3.6 and libaprutil-1.3.8.This is a 64bit machine with ROCKS cluster package installed (CentOS 5.2).

Please see below the libapr* from both /usr/lib and /usr/lib64/

NB: Please note I'm not interested to disable ldap modules in httpd.conf

Please help me out with some solutions to this.

Have you tried rebuilding mod_ldap.so and probably Apache?

 

Thanks for the reply

Answer to your question is NO. but I tried soft linking the lipapr-1.so as suggested by some forums, but nothing worked,

Please suggest a solution to resolve it.

 

I'd rebuild mod_ldap.so as that should make it link against your current version.
