Please replace the keyword myLdapRepository with the actual ldap key. The key can be obtained from the atlassian-user.xml file located in the <bamboo-home>/xml_data/configuration/* directory
Start the Bamboo instance
ℹ️Prior Bamboo v5.8, the LDAP cache mechanism used was "com.atlassian.cache.memory.MemoryCacheManager" and now replaced by "com.atlassian.cache.ehcache.EhCacheManager".
In case you are experiencing the issue, please refer to the following BAM-15360 - Ldap group membership not updated without a restart and the resolution would be to upgrade Bamboo to v5.8+
